Silicone Rubber Features

Excellent flame retardant.
Excellent electric insulation.
Steady-going storage.
Excellent memory and low-stress relaxation reduce maintenance costs associated with gasket failures.
Resistance to ultraviolet light, ozone, and extreme temperatures(-60 ~ 200 oC) enable consistent performance.

Silicone Rubber Applications

It is used to seal and protect various outdoor communications, cell packs, railway transportation, and electronics.
This material provides protection against wind-driven rain and fire, and reduces shock or isolates vibration.
