Silicone foam sealant / Silicone Foam / Airbag Silicone Coating / Optical Grade Liquid Silicone Rubber / Self-lubricating Silicone Rubber / Silicone Gasket / Fluorosilicone Rubber
Silicone rubber, with its excellent resistance to high and low temperatures, electrical insulation, and chemical stability, has become an indispensable key material in modern automobile manufacturing. Its applications cover multiple core systems from traditional fuel vehicles to new energy vehicles, such as powertrain and high-temperature component protection, new energy vehicle battery safety and thermal management, body sealing and NVH performance optimization, and electronic and electrical components and smart cockpits.
Self-lubricating Silicone Rubber
As a high-performance silicone self-lubricating sealing material, it solves the problem of easy damage from dry friction in traditional seals through surface self-lubrication technology. This material is particularly suitable for dynamic sealing scenarios with stringent requirements for tribological performance, sealing durability, and dimensional accuracy.
Main Applications:
Wire harness seals, O-rings, gaskets and various dynamic seals.
