Keywords: high-end silicone demand, medical silicone, automotive silicone, thermal conductive silicone, LSR, biocompatible silicone

• Medical-grade silicone (fastest growth):
  • Global market to reach $3.2 billion in 2026 (CAGR 15.3%); China market 8.5 billion yuan (up 18% YoY).
  • Requires high purity (≤10ppm impurities) and biocompatibility (ISO 10993, FDA compliant).
  • Domestic firms (Dongyue, Hesheng) break foreign monopoly, with local market share reaching 35%.
   
• Automotive silicone (largest segment):
  • Each NEV uses 8–10kg of silicone (2–3x traditional cars), driving demand for thermal greases, pads, and potting adhesives.
  • Global market to hit $5.8 billion in 2026 (CAGR 12.8%); domestic demand up 20% YoY.
   
• Liquid silicone rubber (LSR):
  • Widely used in precision injection molding for auto parts, 3C electronics, and medical devices.
  • Global market $4.1 billion (CAGR 14.5%); domestic capacity 200,000 tons/year (up 25% YoY).
   
• Tech breakthrough: Guangdong firms develop high-thermal-conductivity silicone (5.0 W/(m·K)) for NEV batteries, gaining market traction.
