  • 2026-09-03 Price Trend Daily Report

    Price Overview

    Material Current Price Range WoW Trend
    PTFE Resin General grade ¥50k–54k/t; Electronic grade ¥150k–300k/t +2%~+5% Rising
    PEEK Resin Domestic industrial ¥400–600/kg; Imported ¥800–1,500/kg 0% Stable
    Carbon Fiber T300/12K ¥80–90/kg; T700/12K ¥120–150/kg +1.5% Rising (bottom reversal)
    PI Film Electrical grade ¥110–220/kg; Electronic grade ¥1.0–3.0M/t Electronic +2% Rising (high-end)
    Specialty Ceramic Raw Materials Zirconia ¥56k/t (general); Fused ZrO₂ ¥33k/t +1% Rising

    Key Movements

    • PTFE Resin: general +2%, electronic +5%. Nvidia adopted PTFE as the core material for the Rubin Ultra orthogonal backplane, driving surging AI-computing demand; combined with rising fluorspar/hydrofluoric-acid costs and the industry’s “volume-control, price-protection” stance, the price center keeps moving up. High-end electronic-grade PTFE has exceeded ¥150k/t.
    • Carbon Fiber: T300/12K +1.5% (bottom reversal). Toray raised prices 10%–20% from January; Jilin Chemical Fiber followed; low-altitude-economy (eVTOL, drones) demand is booming, capacity cleanup is taking effect, and inventories are falling.
    • Specialty Ceramic Raw Materials (Zirconia): +1% (cumulative +29% YTD). Sinocera raised zirconia powder prices 10%–40% from July 27; zircon sand rose on geopolitical disruptions, yttria export controls lifted high-end YSZ costs; PCB grinding media, MLCC, and solid-state batteries are pulling demand.
    • PEEK Resin: Stable. Domestic producers (Zhongyan, Junhua) keep expanding and substitution is pressing prices down; industrial grade is flat while imported high-end stays elevated on tight supply.
    • PI Film: Electrical grade steady, electronic grade +2%. Kaneka raised all PI film prices 20% in April; the high-end electronic-grade supply gap is locked through 2027, driven by AI servers, advanced packaging, and foldable displays.

    Impact Analysis

    • Procurement cost: PTFE, zirconia, and high-end PI film keep rising, lifting costs for fluoropolymer and functional-ceramic products; carbon fiber sits at historic lows and PEEK is stable, so overall cost pressure is contained.
    • Supply chain: High-end PI film and high-end zirconia are highly import-dependent; overseas supply cuts and long-term lock-ins tighten supply elasticity—watch FX and geopolitical logistics risks. Carbon fiber and PEEK have ample domestic supply, improving buyer leverage.

    Actionable Recommendations

    • Lock in now: PTFE (especially electronic grade), high-end electronic PI film, yttria-stabilized zirconia—clear upward trend, sign 3–6 month contracts to lock prices.
    • Watch / hold: PEEK industrial grade (domestic expansion pressing prices, buy opportunistically); carbon fiber T300 (bottom-range oscillation, build positions in batches, no need to chase highs).

  • Inteligência Diária de Palavras-chave em Novos Materiais (3 de Setembro de 2026): Onda de Capacidade de PEEK na China e a Norma Obrigatória de Aerogel

    1. Resumo Executivo (Conclusão Primeiro)

    Esta edição monitora seis palavras-chave quentes de novos materiais: PTFE, PEEK, fibra de carbono, cerâmicas técnicas, produtos químicos eletrônicos (químicos eletrônicos úmidos) e aerogel. Leitura geral: alta gama, substituição doméstica e obrigatoriedade regulatória atuam simultaneamente, elevando tanto a popularidade de busca quanto a intenção de compra — mas a estrutura competitiva difere drasticamente entre as seis categorias.

    • Palavra-chave mais quente: PEEK. O Fórum de Tecnologia de Plásticos de Engenharia Especiais PEEK e PPS (organizado pela ASIACHEM) ocorrerá em Nanjing nos dias 10 e 11 de setembro. Somado a isso, os planos de capacidade divulgados para PEEK e plantas integradas na China já excedem 30.000 t/ano (com monômero DFBP de apoio acima de 6.000 t/ano até agosto), levando a densidade de informação setorial ao pico do ano.
    • Maior força regulatória: aerogel. A norma GB 38031-2025 (requisitos de segurança para baterias de tração de veículos elétricos) entrou em vigor em 1º de julho, transformando o aerogel de opcional em obrigatório. A GB/T 46993-2025 para mantas de aerogel na construção civil entrou em vigor em paralelo; o uso por veículo aumentou cerca de 4x em relação a 2023.
    • Reversão de preço confirmada: fibra de carbono. A Toray elevou toda a linha em 10%–20% em janeiro; a Jilin Chemical Fiber aumentou preços duas vezes, acumulando cerca de RMB 10.000/t. O fundo do ciclo já passou, mas a divergência estrutural é severa.
    • Maior lacuna de oferta: produtos químicos eletrônicos. Os químicos úmidos de grau G5 (ultra-alta pureza) têm apenas 10%–30% de localização, deixando uma lacuna de cerca de 70% — o pool de tráfego de cauda longa com maior certeza.
    • Oceanos vermelhos a evitar: resina PTFE comum e fibra de carbono classe T300. Excesso de capacidade de baixa gama e guerras de preços tornam as palavras genéricas de baixa conversão.

    2. Matriz Popularidade / Concorrência / Tendência

    Palavra-chave Popularidade Concorrência Tendência Motor Principal
    PEEK (Poliéter-éter-cetona) ★★★★★ Média (janela de localização) ↑↑ Explosiva Ano de produção em massa de robôs humanoides + onda de capacidade + fórum de setembro
    Aerogel ★★★★★ Média ↑↑ Obrigatória GB 38031-2025 + segurança contra incêndio em armazenamento
    Químicos Eletrônicos (Úmidos) ★★★★★ Alta (gargalo na alta gama) ↑ Forte Expansão de fábricas + computação de IA + 15º Plano Quinquenal
    Fibra de Carbono ★★★★☆ Alta (baixa gama saturada) ↑ Divergente Economia de baixa altitude/eVTOL, espaço comercial, tanques de H2
    Cerâmicas Técnicas ★★★★☆ Alta (oligopólio na alta gama) ↑ Substituição estável Peças de equipamentos semicondutores + substratos de módulos de potência
    PTFE (Politetrafluoroetileno) ★★★☆☆ Média (bifurcada) →↑ Em upgrade Placas de alta frequência para servidores de IA + processos úmidos + regras PFAS

    3. Análise Detalhada por Categoria

    3.1 PEEK: O Ano Decisivo do “Utilizável” para o “Fornecimento em Escala”

    • Tamanho do mercado: O mercado chinês de PEEK foi de ~RMB 2,0 bilhões em 2025, crescendo mais de 15% ao ano; o mercado chinês de resina PPS foi de ~RMB 3,5 bilhões, com crescimento próximo a 10%. O consumo chinês de PEEK em 2026 está projetado em cerca de 4.358 t.
    • Sinal de capacidade: Até agosto de 2026, os planos divulgados de capacidade de PEEK e plantas integradas excedem 30.000 t/ano, com DFBP de apoio acima de 6.000 t/ano. Junhua Holdings (investimento de RMB 1,2 bilhão; 2.000 t PEEK + 500 t LPEEK + 3.000 t fluorenona), Zhongyan Technology e a Lanhai New Materials da PetroChina (piloto de processo contínuo de 300 t/ano) avançam simultaneamente.
    • Cálculo de demanda: O consumo de PEEK por robô humanoide é de 6,6–10 kg. A demanda chinesa apenas deste segmento deve exceder 2.500 t em 2026 (~RMB 2,52 bilhões), com mercado endereçável em 2030 potencialmente acima de RMB 35 bilhões. Em plataformas de 800V, o valor do material PEEK é de RMB 800–1.500 por veículo, com redução de peso de 30%–40%.
    • Faixas de preço: Resina doméstica não carregada ~RMB 250 mil–500 mil/t; graus importados RMB 600 mil–1,5 milhão/t; grau médico RMB 800 mil–1 milhão/t. O material doméstico ainda custa entre metade e um terço do importado.
    • Concorrência: A Victrex detém ~40% de participação; Syensqo e Evonik somam 20%–25%. Note a tensão: o volume da Victrex no exercício de 2025 cresceu 12%, mas no primeiro semestre de 2026 a empresa registrou impairment não caixa de GBP 60,6 milhões nos ativos de Panjin. Uma planta comissionada não é capacidade efetiva — consistência de lote e absorção de mercado são as barreiras reais.
    • Política: O Plano de Ação para Plásticos de Engenharia Especiais de Alto Desempenho (2026–2030), do MIIT e da NDRC, classifica o PEEK como material prioritário de gargalo, com meta de 60% de autossuficiência até 2028 e 80% até 2030.
    • Leitura: Esta é a melhor janela do trimestre para dominar conteúdo de PEEK — espere um pulso de buscas em torno de 10 de setembro. Evite termos genéricos; ataque caudas longas de decisão de compra, como seleção de grau, listas de qualificação e indexação de custo do DFBP.

    3.2 Aerogel: Norma em Vigor, do Opcional ao Obrigatório

    • Tamanho do mercado: O isolamento global de aerogel é de ~USD 4,28–4,59 bilhões em 2026, com CAGR de 15%–18,9%. O segmento de mantas térmicas para baterias cresce de USD 376 milhões (2025) para USD 482 milhões (2026), CAGR de 28,3% — o mais rápido das seis categorias.
    • Mudança de aplicação: Petróleo e gás cai de 56% para ~47%; construção sobe a 14% e transporte a 13%. O aerogel de sílica detém mais de 90% de participação.
    • Política: A GB 38031-2025, em vigor desde 1º de julho, efetivamente insere o aerogel na BOM por meio do requisito de propagação térmica sem fogo nem explosão. A GB/T 46993-2025 fornece a base de seleção para aplicações na construção civil.
    • Adoção: CATL, FinDreams, CALB, Gotion e Sunwoda já adotam em escala.
    • Leitura: Deixe o termo genérico. Vá direto a palavras de cenário: seleção de manta térmica para pack de bateria, barreiras de incêndio para contêineres de armazenamento, custo do aerogel seco à pressão ambiente.

    3.3 Químicos Eletrônicos: Do Dividendo de Escala ao Prêmio Tecnológico

    • Tamanho do mercado: O mercado chinês de químicos eletrônicos úmidos em 2026 está projetado em RMB 18,183–20,0 bilhões, CAGR acima de 12%; o mercado global é de ~USD 6,8–9,0 bilhões. Só a fabricação de CIs requer mais de 1,1 milhão de toneladas por ano.
    • Falha geológica na localização: Graus gerais têm 50%–80% de localização, mas o grau G5 (impurezas metálicas <10 ppt) tem apenas 10%–30%, deixando uma lacuna de cerca de 70%. A localização do fotorresiste ArF permanece abaixo de 1%.
    • Motores: Expansão de fábricas (a China pode chegar a 71 fábricas até 2027), chips de IA, nós abaixo de 3nm, além da designação no 15º Plano Quinquenal e restituição de 13% no imposto de exportação.
    • Barreira: A qualificação junto ao cliente leva de 1 a 3 anos — um fosso natural e um vale da morte para novos entrantes.
    • Leitura: O campo de batalha de conteúdo é a ultra-alta pureza G5 e os químicos úmidos funcionais, combinados com temas de confiança como controle de impurezas metálicas e compressão do ciclo de qualificação.

    3.4 Fibra de Carbono: Piso de Preço Confirmado, Alta Gama Estruturalmente Escassa

    • Preços: Toray +10%–20% em toda a linha a partir de janeiro de 2026; Jilin Chemical Fiber elevou preços duas vezes, acumulando ~RMB 10.000/t. T700 custa RMB 100–140/kg, T800 RMB 180–240/kg, e o grau aeroespacial T1200 RMB 800–1.200/kg.
    • Oferta e demanda: A demanda global em 2026 é de ~142.000 t (+10,9% a/a); a China responde por 52,5% do mundo, com localização acima de 85%.
    • Trilhas de crescimento: Economia de baixa altitude (conteúdo de compósitos em eVTOL acima de 70%), espaço comercial (CAGR acima de 30%), robôs humanoides (5–7 kg por unidade) e tanques de hidrogênio Tipo IV (a fibra representa 60% do custo do vaso).
    • Leitura: T300/T400 comum é brutalmente competitivo; T800 e superior permanece escasso e com prêmio. O conteúdo deve liderar com qualificação doméstica de alta gama, não com preço.

    3.5 Cerâmicas Técnicas: O Osso Mais Duro da Localização de Semicondutores

    • Tamanho do mercado: As cerâmicas técnicas globais somam ~USD 15,1 bilhões em 2026 (CAGR 6,7%); o mercado chinês de cerâmicas avançadas é de ~USD 41,26 bilhões, ou 41,8% do mundo. A demanda por peças cerâmicas de equipamentos semicondutores cresce 14,2%.
    • Localização: As cerâmicas estruturais avançadas têm apenas ~19%–20% de localização; mandris eletrostáticos e aquecedores cerâmicos são praticamente espaços vazios para fornecedores domésticos.
    • Foco técnico: Mandris eletrostáticos (ESC), substratos cerâmicos (AMB/DPC) e HTCC/LTCC são os campos centrais de substituição. As esferas cerâmicas de precisão de nitreto de silício crescem de USD 273 milhões (2025) para USD 830 milhões (2032), CAGR de 17,5%.
    • Gargalo: Pós de alta gama e equipamentos de sinterização permanecem parcialmente dependentes de importação — o gargalo a montante por trás do gargalo.
    • Leitura: Esta é a trilha com consultas B2B de maior qualidade entre as seis: tickets grandes e cadeias de decisão claras. O conteúdo deve mapear números de peça e plataformas de equipamento específicos.

    3.6 PTFE: Bifurcação se Aprofunda, Grau Eletrônico é a Única Saída de Valor

    • Tamanho do mercado: O PTFE global é de ~USD 3,0–4,3 bilhões em 2026, com CAGR de 5,7%–7,2%, e a Ásia-Pacífico representa 52% do consumo. A demanda aparente chinesa é de ~116 kt contra capacidade de ~230 kt, operando a apenas 60%–65%.
    • Estratificação de preço: A resina de suspensão de grão médio custa ~RMB 43.500–48.000/t, enquanto o grau eletrônico se aproxima de RMB 150.000/t — cerca de 3x o grau padrão.
    • Estrutura: O CR5 é de ~62%; Daikin, Chemours e Dongyue somam ~47%. O excesso de oferta na baixa gama é de ~30%; a dependência de importação na alta gama é de ~27%.
    • Crescimento: Emulsão de dispersão e pó fino é o segmento que cresce mais rápido (~+8,9%), impulsionado por revestimento de separadores de íon-lítio e laminados de alta frequência para 5G/IA. A NVIDIA confirmou PTFE modificado com SiO2 para os backplanes ortogonais Rubin Ultra. PFA/PTFE ultrapuro para processos úmidos de semicondutores é alvo de substituição acelerada.
    • Risco: As regras PFAS/PFOA continuam a se apertar enquanto os custos de fluorita e HF permanecem elevados; a transição para fluoropolímeros de cadeia curta é inevitável.
    • Leitura: Abandone as palavras-chave de resina comum. Ataque PTFE grau semicondutor, revestimento PTFE para separadores de íon-lítio, e-PTFE médico e alternativas ao PFAS.

    6. Notas de Risco

    • Risco de materialização da capacidade de PEEK: O impairment de Panjin da Victrex é um alerta claro — existe um intervalo de 2 a 3 anos entre capacidade planejada e capacidade efetiva. Não trate capacidade anunciada como oferta.
    • Atualidade dos dados de preço: Cotações spot de PEEK de até RMB 780.000/t apareceram em janelas de escassez. São valores pontuais, não âncoras de orçamento anual.
    • Excedente de estoque de fibra de carbono: O estoque setorial permanece elevado e os aumentos são de custo (acrilonitrila), não de demanda; os preços podem recuar se a demanda final não confirmar.

  • Daily Advanced Materials Keyword Intelligence (September 3, 2026): China PEEK Capacity Wave and the Aerogel Mandate

    1. Executive Summary (Conclusion First)

    This edition tracks six hot advanced-materials keywords: PTFE, PEEK, carbon fiber, technical ceramics, electronic chemicals (wet electronic chemicals), and aerogel. Overall read: high-endization, domestic substitution, and regulatory compulsion are firing simultaneously, lifting both search heat and purchase intent — but the competitive structure differs sharply across the six categories.

    • Hottest keyword: PEEK. The PEEK & PPS Specialty Engineering Plastics Technology Forum (organized by ASIACHEM) convenes in Nanjing on September 10–11. Combined with disclosed domestic PEEK and integrated-plant capacity plans now exceeding 30,000 t/yr (with supporting DFBP monomer above 6,000 t/yr as of August), industry information density has hit a year-to-date peak.
    • Strongest regulatory pull: aerogel. GB 38031-2025 (EV traction battery safety requirements) took effect July 1, turning aerogel from optional to mandatory. GB/T 46993-2025 for building aerogel blankets landed in parallel; per-vehicle usage is up roughly 4x versus 2023.
    • Price reversal confirmed: carbon fiber. Toray raised its full line 10%–20% in January; Jilin Chemical Fiber lifted prices twice for a cumulative ~RMB 10,000/t. The cycle bottom is behind us, but structural divergence is severe.
    • Largest supply gap: electronic chemicals. G5-grade ultra-high-purity wet chemicals are only 10%–30% localized, leaving roughly a 70% gap — the highest-certainty long-tail traffic pool.
    • Red oceans to avoid: commodity PTFE resin and T300-class carbon fiber. Low-end overcapacity and price wars make generic keywords convert poorly.

    2. Heat / Competition / Trend Matrix

    Keyword Search Heat Competition Trend Core Driver
    PEEK (Polyetheretherketone) ★★★★★ Medium (localization window) ↑↑ Explosive Humanoid robot mass-production year + capacity wave + Sept forum
    Aerogel ★★★★★ Medium ↑↑ Mandated GB 38031-2025 + energy-storage fire safety
    Electronic Chemicals (Wet) ★★★★★ High (high-end bottleneck) ↑ Strong Fab expansion + AI compute + 15th Five-Year Plan
    Carbon Fiber ★★★★☆ High (low-end overcrowded) ↑ Divergent Low-altitude economy/eVTOL, commercial space, H2 tanks
    Technical Ceramics ★★★★☆ High (high-end oligopoly) ↑ Steady substitution Semiconductor equipment parts + power-module substrates
    PTFE (Polytetrafluoroethylene) ★★★☆☆ Medium (bifurcated) →↑ Upgrading AI server high-frequency boards + semi wet process + PFAS rules

    3. Category Deep Dive

    3.1 PEEK: The Pivotal Year from “Usable” to “Scale Supply”

    • Market size: China’s PEEK market was ~RMB 2.0 billion in 2025, growing 15%+ annually; China’s PPS resin market was ~RMB 3.5 billion, growing near 10%. China’s 2026 PEEK consumption is projected near 4,358 t.
    • Capacity signal: As of August 2026, disclosed PEEK and integrated-plant capacity plans exceed 30,000 t/yr with supporting DFBP above 6,000 t/yr. Junhua Holdings (RMB 1.2 billion investment; 2,000 t PEEK + 500 t LPEEK + 3,000 t fluorenone), Zhongyan Technology, and PetroChina’s Lanhai New Materials (300 t/yr continuous-process pilot) are all advancing.
    • Demand math: Per-unit PEEK content in humanoid robots is 6.6–10 kg. China’s 2026 demand from this segment alone should exceed 2,500 t (~RMB 2.52 billion), with the 2030 addressable market potentially above RMB 35 billion. On 800V EV platforms, PEEK material value is RMB 800–1,500 per vehicle at 30%–40% weight savings.
    • Price bands: Domestic unfilled resin ~RMB 250k–500k/t; imported grades RMB 600k–1,500k/t; medical grade RMB 800k–1,000k/t. Domestic still prices at one-half to one-third of imported.
    • Competition: Victrex holds ~40% share; Syensqo plus Evonik together 20%–25%. Note the tension: Victrex FY2025 volume rose 12%, yet in H1 2026 it booked a GBP 60.6 million non-cash impairment on its Panjin assets. A commissioned plant is not effective capacity — batch consistency and market absorption are the real barriers.
    • Policy: MIIT and NDRC’s High-Performance Specialty Engineering Plastics Action Plan (2026–2030) names PEEK a priority chokepoint material, targeting 60% self-sufficiency by 2028 and 80% by 2030.
    • Read: This is the best window of the quarter to claim PEEK content — expect a search pulse around September 10. Avoid generic terms; attack procurement-decision long-tails such as grade selection, qualification checklists, and DFBP cost indexation.

    3.2 Aerogel: Standard Landed, Optional Becomes Mandatory

    • Market size: Global aerogel insulation is ~USD 4.28–4.59 billion in 2026 at 15%–18.9% CAGR. The battery thermal-pad segment grows from USD 376 million (2025) to USD 482 million (2026), a 28.3% CAGR — the fastest of all six categories.
    • Application shift: Oil and gas falls from 56% to ~47%; construction rises to 14% and transport to 13%. Silica aerogel holds over 90% share.
    • Policy: GB 38031-2025, effective July 1, effectively writes aerogel into the BOM via its no-fire/no-explosion thermal-propagation requirement. GB/T 46993-2025 provides the selection basis for building applications.
    • Adoption: CATL, FinDreams, CALB, Gotion and Sunwoda have all adopted at scale.
    • Read: Skip the generic term. Go straight to scenario keywords: battery-pack thermal pad selection, ESS container fire barriers, ambient-pressure-dried aerogel cost.

    3.3 Electronic Chemicals: From Scale Dividend to Technology Premium

    • Market size: China’s 2026 wet electronic chemicals market is projected at RMB 18.183–20.0 billion, CAGR 12%+; the global market is ~USD 6.8–9.0 billion. IC manufacturing alone requires over 1.1 million tonnes per year.
    • Localization fault line: General grades are 50%–80% localized, but G5 grade (metal impurities <10 ppt) is only 10%–30%, leaving roughly a 70% gap. ArF photoresist localization remains below 1%.
    • Drivers: Fab expansion (China’s fab count could reach 71 by 2027), AI chips, sub-3nm nodes, plus 15th Five-Year Plan designation and a 13% export tax rebate.
    • Barrier: Customer qualification takes 1–3 years — a natural moat and a death valley for new entrants.
    • Read: The content battleground is G5 ultra-high purity and functional wet chemicals, paired with trust-building topics like metal impurity control and qualification cycle compression.

    3.4 Carbon Fiber: Price Floor Confirmed, High End Structurally Tight

    • Pricing: Toray +10%–20% across the line from January 2026; Jilin Chemical Fiber raised prices twice for ~RMB 10,000/t cumulative. T700 runs RMB 100–140/kg, T800 RMB 180–240/kg, and aerospace-grade T1200 RMB 800–1,200/kg.
    • Supply-demand: Global 2026 demand is ~142,000 t (+10.9% YoY); China accounts for 52.5% of the world with 85%+ localization.
    • Growth tracks: Low-altitude economy (eVTOL composite content above 70%), commercial space (CAGR above 30%), humanoid robots (5–7 kg per unit), and Type-IV hydrogen tanks (fiber is 60% of vessel cost).
    • Read: Commodity T300/T400 is brutally competitive; T800 and above remains tight and premium-priced. Content should lead with domestic high-end qualification, not price.

    3.5 Technical Ceramics: The Hardest Bone in Semiconductor Localization

    • Market size: Global technical ceramics is ~USD 15.1 billion in 2026 (CAGR 6.7%); China’s advanced ceramics market is ~USD 41.26 billion, or 41.8% of the world. Demand for semiconductor equipment ceramic parts is growing 14.2%.
    • Localization: Advanced structural ceramics are only ~19%–20% localized; electrostatic chucks and ceramic heaters are near-blank spaces for domestic suppliers.
    • Technical focus: Electrostatic chucks (ESC), ceramic substrates (AMB/DPC), and HTCC/LTCC are the core substitution battlegrounds. Silicon nitride precision ceramic balls grow from USD 273 million (2025) to USD 830 million (2032), a 17.5% CAGR.
    • Bottleneck: High-end powders and sintering equipment remain partly import-dependent — the upstream chokepoint behind the chokepoint.
    • Read: This is the highest-quality B2B inquiry track of the six: large ticket sizes and clear decision chains. Content should map to specific part numbers and equipment platforms.

    3.6 PTFE: Bifurcation Deepens, Electronic Grade Is the Only Value Exit

    • Market size: Global PTFE is ~USD 3.0–4.3 billion in 2026 at 5.7%–7.2% CAGR, with Asia-Pacific at 52% of consumption. China’s apparent demand is ~116 kt against ~230 kt capacity, running at just 60%–65% utilization.
    • Price tiering: Suspension medium-granule resin is ~RMB 43,500–48,000/t, while electronic grade approaches RMB 150,000/t — roughly 3x standard grade.
    • Structure: CR5 is ~62%; Daikin, Chemours and Dongyue together hold ~47%. Low-end oversupply is ~30%; high-end import dependence is ~27%.
    • Growth: Dispersion emulsion and fine powder is the fastest-growing segment (~+8.9%), pulled by Li-ion separator coating and 5G/AI high-frequency CCL. NVIDIA has confirmed SiO2-modified PTFE for Rubin Ultra orthogonal backplanes. Ultra-pure PFA/PTFE for semiconductor wet processes is a fast-moving substitution target.
    • Risk: PFAS/PFOA rules keep tightening while fluorite and HF costs stay elevated; short-chain fluoropolymer transition is now unavoidable.
    • Read: Abandon commodity-resin keywords. Attack semiconductor-grade PTFE, Li-ion separator PTFE coating, e-PTFE medical, and PFAS alternatives.

    6. Risk Notes

    • PEEK capacity realization risk: The Victrex Panjin impairment is a clear warning — a 2–3 year gap sits between planned and effective capacity. Do not treat announced capacity as supply.
    • Price data currency: PEEK spot quotes as high as RMB 780,000/t appeared during tight windows. Those are point-in-time prints, not annual budget anchors.
    • Carbon fiber inventory overhang: Industry inventory remains elevated and the hikes are cost-push (acrylonitrile) rather than demand-pull; prices could retrace if end demand fails to confirm.

    • 需求测算：人形机器人单机 PEEK 用量 6.6–10kg，2026年国内该领域需求预计超 2500吨、对应约 25.2亿元；2030年长期空间有望突破 350亿元。800V 高压平台单车 PEEK 材料价值 800–1500元，减重 30%–40%。
    • 价格带：国产未填充树脂约 25–50万元/吨，进口牌号 60–150万元/吨，医疗级 80–100万元/吨。国产对进口的价差仍在 1/2–1/3 区间。
    • 竞争格局：Victrex 约 40% 份额，Syensqo + Evonik 合计 20%–25%。值得注意的是 Victrex 2025财年销量同比 +12%，但 2026上半年对盘锦基地计提 6060万英镑非现金减值——建成装置 ≠ 有效产能，批次一致性与市场消化是真门槛。
    • 政策：工信部、发改委《高性能特种工程塑料产业高质量发展行动方案（2026–2030年）》将 PEEK 列为「卡脖子」重点攻关品种，2028年国产自给率 60%、2030年 80%。
    • 研判：本周是 PEEK 内容抢位的最佳窗口——9月10日论坛前后行业搜索量会出现脉冲。但要避开泛词，主攻「牌号选型」「验证清单」「DFBP成本联动」等采购决策类长尾。

    2. 气凝胶：强标落地，从渗透走向刚需

    • 市场规模：2026年全球气凝胶隔热材料约 42.8–45.9亿美元，CAGR 15%–18.9%；电池隔热垫细分从 2025年 3.76亿美元增至 2026年 4.82亿美元，CAGR 28.3%——六大品类中增速第一。
    • 应用结构迁移：油气从 56% 降至约 47%，建筑升至 14%、交通 13%。二氧化硅气凝胶占比超 90%。
    • 政策：GB 38031-2025 于 7月1日实施，热扩散不起火不爆炸要求实质上把气凝胶写入了 BOM；GB/T 46993-2025 建筑用气凝胶毯标准为建筑场景提供了选型依据。
    • 头部导入：宁德时代、弗迪电池、中创新航、国轩、欣旺达均已规模化采用。
    • 研判：不要打「气凝胶」泛词，直接打场景词——「电池包隔热垫选型」「储能舱防火隔热」「常压干燥气凝胶成本」。

    3. 电子化学品：从「规模红利」转向「技术溢价」

    • 市场规模：2026年中国湿电子化学品市场预计 181.83–200亿元，CAGR 12%+；全球约 68–90亿美元。IC 制造对湿电子化学品的年需求量超 110万吨。

    • 驱动：晶圆厂扩产（2027年中国晶圆厂数量或达 71座）、AI 芯片、3nm 以下先进制程、十五五规划点名 + 13% 出口退税。
    • 壁垒：客户认证周期 1–3年，是天然护城河也是新进入者的死亡谷。
    • 研判：内容主战场是 G5级超高纯与功能性湿化学品，配合「认证周期」「金属杂质控制」等技术信任类内容。

    4. 碳纤维：价格底部确认，高端结构性紧缺

    • 价格：东丽2026年1月全线提价 10%–20%；吉林化纤年内两次提价累计约 1万元/吨。T700 约 100–140元/kg，T800 约 180–240元/kg，宇航级 T1200 达 800–1200元/kg。
    • 供需：2026年全球需求约 14.2万吨（同比 +10.9%），中国占全球 52.5%，国产化率 85%+。
    • 增量赛道：低空经济（eVTOL 机体复材占比 >70%）、商业航天（CAGR >30%）、人形机器人（单机 5–7kg）、IV型储氢瓶（碳纤维占瓶体成本 60%）。
    • 研判：通用级 T300/T400 内卷严重，T800 及以上仍紧缺且带溢价。内容主线应是「国产高端验证」而非「价格」。

    5. 特种陶瓷：半导体设备国产化的硬骨头

    • 市场规模：2026年全球技术陶瓷约 151亿美元（CAGR 6.7%）；中国先进陶瓷约 412.6亿美元，占全球 41.8%。半导体设备陶瓷零部件需求增速 14.2%。
    • 国产化率：先进结构陶瓷整体国产化率仅约 19%–20%，静电卡盘、陶瓷加热器等高价值件几乎是空白区。
    • 技术焦点：静电卡盘（ESC）、陶瓷基板（AMB/DPC）、HTCC/LTCC 是替代核心战场；氮化硅精密陶瓷球 2025年 2.73亿美元 → 2032年 8.3亿美元（CAGR 17.5%）。
    • 瓶颈：高端粉体与烧结装备仍部分依赖进口，这是国产替代的「上游卡点」。
    • 研判：这是六个品类中B2B询盘质量最高的赛道——单笔金额大、决策链清晰。内容应对标具体零部件与设备型号。

    6. PTFE：两极分化加剧，电子级是唯一价值出口

    • 市场规模：2026年全球 PTFE 约 30–43亿美元，CAGR 5.7%–7.2%，亚太占消费量 52%。中国表观需求约 11.6万吨，产能约 23万吨但开工率仅 60%–65%。
    • 价格分层：悬浮中粒树脂约 4.35–4.8万元/吨；电子级接近 15万元/吨，约为标准级3倍。
    • 结构：CR5 约 62%，大金、科慕、东岳合计约 47%。低端过剩约 30%，高端依赖度约 27%。
    • 增长点：分散乳液/细粉是增速最快细分（约 +8.9%），受锂电隔膜涂覆与 5G/AI 高频覆铜板拉动；NVIDIA 已确认 SiO₂ 改性 PTFE 用于 Rubin Ultra 正交背板。半导体湿制程超纯 PFA/PTFE 是快速替代标的。
    • 风险：PFAS/PFOA 监管持续收紧，萤石、氢氟酸成本高位，短链氟聚合物转型是必答题。
    • 研判：坚决放弃通用树脂词，主攻「半导体级PTFE」「锂电隔膜PTFE涂覆」「e-PTFE医用」「PFAS替代方案」。
