Unique Properties of Silicone
Temperature Resistance: Maintains stability from -60°C to 300°C, with some products enduring higher extremes.
Chemical Inertness: Resistant to UV, ozone, and most chemical reagents, ensuring long service life.
Biocompatibility: Medical-grade silicones are used in implants and prosthetics.
Excellent Electrical Insulation: Critical for electronic component encapsulation.
Key Applications
Construction: Sealants (e.g., structural glazing), waterproof coatings
Electronics: Chip packaging, conductive rubber keys
Healthcare: Catheters, prosthetics, scar sheets
Personal Care: Shampoos (dimethicone), foundation
New Energy: PV module sealing, lithium battery thermal pads
Industry Trends
China now leads global silicone production, accounting for over 60% of 2023 capacity. Specialty silicones (e.g., high-thermal-conductivity variants, liquid silicone rubber) are in growing demand for EVs and 5G applications. Experts project the global market to exceed $30 billion by 2026.
Environmental Challenges
While silicone itself is non-toxic, byproduct management in production requires improvement. The industry is advancing green technologies like fluidized-bed direct synthesis of methyl chlorosilane.
