800V High-Voltage EV Platform Boosts Demand for High Withstan
Keywords: 800V EV platform, high voltage resistant silicone, new energy vehicle sealing, flame retardant LSR, automotive silicone
Key Sentence: Popularization of 800V fast-charging vehicles pushes high withstand voltage silicone to become standard matching material for new energy powertrains.
Global mainstream auto brands are comprehensively switching to 800V high-voltage electric vehicle platforms in 2026, bringing explosive growth to high insulation silicone products. Special modified liquid silicone rubber can withstand voltage above 3kV/mm, with UL94 V-0 flame retardant grade, low volatile and long-term high-temperature aging resistance. It is applied to high-voltage wire harness seals, battery module edge sealing and charging gun waterproof parts. Market data shows the market scale of high-voltage automotive silicone will exceed $7.2 billion within this year. Chinese silicone factories with automotive-grade IATF16949 certification gain more overseas OEM orders, and customized high-temperature resistant silicone formulas become core competitive advantages.
