Domestic Low-Viscosity Fast-Curing Automotive LSR Realizes Mass Production, Matches 800V EV High-Voltage Sealing Demand
2026,07,21
Key Sentence: Self-developed low-viscosity fast-curing liquid silicone shortens molding cycle by 22%, fully meets mass production requirements of high-voltage components for high-voltage electric vehicles.
On July 20, 2026, silicone material manufacturers in Guangdong officially launched a new generation of automotive-specific liquid silicone rubber after two years of formula iteration. This modified LSR features ultra-low viscosity and rapid platinum curing, effectively solving the slow filling and long production cycle problems of traditional liquid silicone in thin-walled high-voltage wire harness seals and charging gun gaskets.
The material passes IATF16949 automotive grade certification, with insulation strength exceeding 3.5kV/mm and UL94 V-0 flame retardant performance, stable under -40℃ to 180℃ long-term alternating temperature environment. Domestic new energy vehicle parts factories have replaced imported LSR in batches, cutting material comprehensive procurement cost by nearly 25%.
Industry data shows the global 800V high-voltage platform vehicle output will grow 40% year-on-year in H2 2026, driving continuous growth of high-performance automotive LSR orders. Domestic liquid silicone enterprises with complete automotive certification systems will further seize global auto parts material supply market share.
