Fiberglass Reinforced Flame Retardant Silicone sponge is an excellent material for gasketing applications that require a compressible material. The Fiberglass gives it dimensional stability which also helps in cutting close tolerance parts. It is resistant to extreme temperatures. It comes in a dark blue/grey color. The surface has a fine fabric finish on both sides and is available in continuous rolls up to 1/2" thick.
