Investment Scale: Zhongyan (688716) plans CNY 1.2B investment in Zhangjiagang for 10,000t/yr PEEK + 2,000t/yr fluoroketone integrated project
Strategic Value: Achieve upstream fluoroketone self-sufficiency, reduce raw material costs, improve profit margins
Applications: Aerospace, automotive, electronics, medical, 3D printing and other high-end manufacturing
Price Stability: Industrial PEEK prices stable; 450G (general injection grade) fluctuation ≤5%; 150G (powder/coating grade) fluctuation ≤8%
Supply Capability: Shangfu New Materials maintains 60-ton spot inventory, 48-hour delivery

Capacity Breakthrough: Sinopec commissions China’s largest single-line large-tow carbon fiber production line in Inner Mongolia, with single-line capacity exceeding 3,000 tons
Project Progress: Inner Mongolia Xinjinshan 30,000-ton carbon fiber Phase I starts production with 6,000-ton annual capacity; Phase II with 8 production lines expected to complete by end 2027, reaching 30,000-ton total capacity
Technology Breakthrough: Domestic T1000 carbon fiber achieves mass production; single filament can bear ~200kg load; China becomes third country after Japan and US to master T1000 technology
Tech Progress: Heshun Tech (301237.SZ) subsidiary Hexing Carbon Fiber HM46J carbon fiber trial successful, performance meets international advanced standards
Sector Performance: Carbon fiber concept index BK1171 reports 1,969.72 points, +0.22%

Premium Pricing: PI film for folding screen mobile phones can reach CNY 20-30 million per ton, comparable to gold
Low Localization: Over 70% of high-end demand relies on imports; over 60% of global market controlled by DuPont, Kaneka, and PIAM
Market Size: Global PI film market ~USD 4.68B in 2025; China market ~CNY 10.8B
Capacity Mismatch: China’s total PI film capacity exceeds 110,000 tons, but self-sufficiency rate for high-end electronic/optical grade products only 20-30%
Domestic Progress: Guofeng New Materials has 12 high-performance PI film production lines (4 under construction), entering global first tier; PI chip-on-film samples submitted for chip packaging
Performance Advantage: PI can operate stably in extreme temperatures from -269°C to 400°C, with insulation strength higher than many metal sheets

Leading Performance: Aerogel nano insulation film thermal conductivity as low as 0.018 W/(m·K), only 1/20 of ordinary glass
Leading Enterprises: Fanrui Yihui focuses on nano-silica aerogel, carbon fiber reinforced ceramic matrix composites; Honghui Tech participates in drafting GB/T 46993-2025 and other aerogel national standards
Application Scenarios: Power battery thermal pads, new energy vehicle fire blankets, pipe insulation, building energy saving
Technology Upgrade: Aerogel nano insulation film integrates vanadium dioxide thermochromic material, achieving “temperature-adaptive” dynamic regulation

Wide Applications: PTFE high-temperature fabrics applied in photovoltaic, food, chemical, electronics, environmental protection and other fields
Temperature Resistance: Operating temperature range -70°C to 260°C (long-term), short-term resistance up to 300°C
Glass Furnace Application: PTFE filter bags show clear advantages in glass furnaces – high temp/corrosion resistance, easy cleaning, good emission control, cost-effective
Product Pricing: PTFE filter bags approximately 80 CNY/piece
Representative Enterprise: Jiangsu Aokai New Materials is the source manufacturer for PTFE high-temperature fabrics

PEEK: Lock in existing premium supplier capacity before Zhongyan expansion; post-commissioning price decline expected
Carbon Fiber: Large-tow capacity release creates purchasing window; T1000 localization accelerates high-end applications
PI Film: Large substitution space for high-end folding screen PI; prioritize domestic suppliers like Guofeng New Materials
Aerogel: Strong demand from power battery fire protection; focus on niche leaders like Fanrui Yihui and Honghui Tech
PTFE: Stable demand in industrial filtration; focus on direct procurement from source manufacturers
