Key Sentence: Rapid penetration of 800V high-voltage platforms drives domestic automotive-grade liquid silicone production capacity release, with monthly output of special LSR for new energy vehicles hitting a new high in August.
On August 4, 2026, operation data of silicone industrial parks in South China shows the monthly output of high-insulation liquid silicone for new energy vehicles increases by 29% month-on-month, mainly applied to high-voltage wire harness sealing sleeves, charging gun gaskets and battery PACK shock-absorbing sealing components of 800V fast-charging electric vehicles. This automotive LSR passes strict high-voltage insulation testing with breakdown strength above 3.6kV/mm, stable operation under long-term alternating temperature of -40℃~180℃, and possesses UL94 V-0 flame retardant performance to meet the safety standards of mainstream global new energy vehicle brands. Local auto parts manufacturers gradually realize localized replacement of imported automotive LSR; silicone factories build exclusive automated injection molding production lines to guarantee stable product consistency and shorten molding cycles by about 20%. Traditional low-end general industrial silicone orders are affected by summer off-season with sluggish growth, while new energy automotive silicone becomes the main revenue pillar for silicone deep-processing enterprises. Industry forecast indicates global 800V EV production will surge over 40% year-on-year in H2 2026, continuously driving sustained growth demand of high-performance automotive liquid silicone and bringing stable profit growth space for certified silicone manufacturers.
