2026-07-19 Price Trend Daily Report

1. Price Overview

Material	Current Price Range	WoW	Trend
PTFE Resin	30k–52k CNY/ton	-4%	Down
PEEK Resin	Domestic 370k–400k CNY/ton; Import 900k–1.5M CNY/ton	+1%	Stable (structural upside)
Carbon Fiber	T300 grade 78k–95k CNY/ton; T700 grade 118k CNY/ton	+1.5%	Up
PI Film	Electronic grade ≥1M CNY/ton	+2%	Up
Specialty Ceramic Raw Materials	Zirconia 89k CNY/ton; Nano alumina 150k CNY/ton	0%	Stable

2. Key Movements

PTFE Resin: -4%. Major quotes in East China and Shandong fell to 34k–50k CNY/ton; Luxi Chemical quoted 34k CNY/ton on Jul 17, down 1k from the prior day. Drivers: (1) anhydrous HF eased from its early-year peak (above 16k CNY/ton, ~+40% YTD) back to ~15k CNY/ton, weakening cost support; (2) new capacity keeps supply ample; (3) downstream buys only to need, thin trading — supply surplus persists.
Carbon Fiber: +1.5%. Toray raised TORAYCA series by 10%–20% from Jan 2026; Jilin Chemical followed (12K and 3K up 5k and 10k CNY/ton respectively), T300 12K around 95k CNY/ton. Prices are recovering from the post-overcapacity bottom as demand from wind power, hydrogen storage cylinders, robotics and auto light-weighting rebounds.
PI Film: +2%. Electronic grade (biaxially oriented) trades above 1M CNY/ton, heavily import-dependent and concentrated among DuPont, Ube, Kaneka, SK Kolon. EV, 5G and flexible electronics drive strong demand, creating a structural shortage.

3. Impact Analysis

Procurement cost: Rising carbon fiber and PI film directly lift costs of advanced composites and electronic substrates; monthly gains already squeeze margins. Falling PTFE frees some cost room, but watch quality of low-end grades.
Supply chain: Carbon fiber and PI film rely heavily on imports; Toray and peers hold pricing power, so geopolitics/trade policy can trigger supply risk — build a multi-supplier base and strategic stock. PEEK localization is accelerating (domestic share ~60% by 2026), improving local supply security.

4. Action Recommendations

Lock prices: Carbon fiber, PI film — clear upward trend and concentrated supply; sign mid/long-term contracts or lock in batches to avoid further hikes.
Wait and see: PTFE resin — still in a downtrend, delay bulk orders and restock as needed; PEEK resin and ceramic raw materials are stable, maintain a normal procurement rhythm.
