HT820 Flame Retardant Silicone Sponge Sheet
HT820 flame retardant silicone sponge sheeting (firm density). Boasting higher tear and tensile strength than lighter grade foams, this product offers superior durability and sealing.
It has excellent memory and low stress relaxation, making it an ideal gasketing material. Further, its resistance to UV, Ozone, extreme temperature and flame allow it to be used in all environments and its cell structure prevents penetration by fine particles and rain.
Possible applications include, but are not limited to gaskets, anti-vibration/cushioning, HVAC systems, anti-fogging seals and battery pads/cushions in the automotive industry.
This sheeting is 915mm wide and is sold by the metre.
