    | Special Ceramic Raw Materials | 4,500-12,000 RMB/kg | +1.2% | Slightly Rising |

    ## Key Changes

    ### PTFE Resin: Weekly Decline of 3.6%
    – **Current Price**: 31,800-33,000 RMB/ton
    – **Change Analysis**: According to chemicalbook.com data, PTFE price on June 14 was 31,800 RMB/ton, down 3.6% from 33,000 RMB/ton on June 9
    – **Influencing Factors**:
    – Declining raw material costs: Upstream chlorodifluoromethane (R22) prices weakening
    – Sufficient supply: Major domestic producers like Shandong Dongyue and Fuxin Hengtong maintain normal operating rates with stable supply despite low inventory
    – Weak demand: Procurement slowing in downstream chemical and electronics industries

    ### Carbon Fiber: Weekly Increase of 2.5%
    – **Current Price**: 80-120 RMB/kg (T300 grade)
    – **Change Analysis**: Prices rising moderately driven by demand from aerospace and new energy vehicles
    – **Influencing Factors**:
    – Growing demand: Increasing commercial aircraft orders, sustained demand for wind turbine blades and automotive lightweighting
    – Tight capacity: High-end carbon fiber still relies on imports; domestic capacity expansion takes time
    – Raw material costs: Acrylonitrile price fluctuations affect production costs

    ### Special Ceramic Raw Materials: Slight Increase of 1.2%
    – **Current Price**: 4,500-12,000 RMB/kg (rare earth ceramic additives like high-purity dysprosium oxide)
    – **Change Analysis**: Prices of rare earth ceramic additives rising slightly
    – **Influencing Factors**:
    – Rare earth price rebound: National reserve policies supporting prices of dysprosium oxide, terbium oxide, etc.
    – Growing electronic ceramic demand: Increased demand for dielectric ceramics from 5G base stations and new energy vehicles
    – Supply concentration: China dominates global rare earth supply; policy impacts significant

    ## Impact Analysis

    ### Impact on Procurement Costs
    1. **PTFE Resin**: Price decline reduces raw material costs for seals, pipe linings, and other products; appropriate to increase inventory currently
    2. **Carbon Fiber**: Price increase raises composite material costs; recommend locking in long-term supply contracts
    3. **Special Ceramic Raw Materials**: Rising rare earth raw material prices create cost pressure for electronic ceramic and dielectric ceramic producers

    ### Impact on Supply Chain
    1. **Supply Stability**: PTFE and PEEK supply stable; high-end carbon fiber still relies on imports, posing supply chain risks
    2. **Inventory Strategy**: PTFE can be stocked up at current low prices; carbon fiber requires advance orders to secure supply
    3. **Alternative Solutions**: Consider using PFA, FEP as PTFE alternatives; explore bio-based composite materials as carbon fiber substitutes

    ## Action Recommendations

    ### Materials Recommended to Lock in Prices
    1. **Carbon Fiber**: Price increase trend clear; recommend signing long-term supply agreements with major domestic producers (e.g., Zhongfu Shenying, Guangwei Composites)
    2. **Special Ceramic Raw Materials (Rare Earth Class)**: Prices in upward channel; recommend advance procurement of high-purity dysprosium oxide, terbium oxide, etc.

    ### Materials Recommended to Wait-and-See
    1. **PTFE Resin**: Prices in declining channel; recommend batch procurement, avoid large one-time stockpiling
    2. **PEEK Resin**: Prices stable, supply sufficient; procure as needed
    3. **PI Film**: Prices stable, technology mature; recommend maintaining regular procurement pace

    ## Market Outlook

    **Short-term (1-3 months)**:
    – PTFE resin prices may continue weak oscillation; monitor upstream R22 prices and downstream demand recovery
    – Carbon fiber prices will remain high, supported by both demand and capacity constraints
    – Special ceramic raw material prices subject to rare earth policy influences, uncertainty exists

    **Medium-to-Long term (6-12 months)**:
    – Strategic emerging industries like new energy, 5G, and aerospace will continue driving high-end new material demand
    – Gradual release of domestic new material capacity, accelerated import substitution will help stabilize prices
    – Monitor changes in national new material industry policies, environmental policies, and international trade situation
