Key sentence: Oil-exuding liquid silicone rubber forms an in-situ lubricating layer while resisting glycol coolant, simplifying mass assembly for EV battery cooling circuit seals.

正文： Material developers release innovative oil-exuding LSR specially designed for EV traction battery cooling loop connectors. When cured, the silicone continuously releases a thin silicone oil film on the surface, reducing friction during automated assembly. Unlike older self-lubricating silicone grades, this new formulation maintains stable performance after long contact with glycol-based battery coolant.

It features low compression set and high tear strength to preserve sealing performance over the full battery service life. EV tier 1 suppliers are carrying out reliability validation for battery pack quick connectors and cooling pipe gaskets. This material reduces assembly lubricant spraying steps and lowers defect rates on automotive production lines. Demand for high-performance specialty silicone continues rising as EV battery production scales up worldwide.
