KoolMat is a space age material used in thousands of commercial, industrial and automotive applications. KoolMat is a composite material of silicone cured to the surface and weave of a high temperature fiberglass substrate. Weighing .72 per sq. foot and a thickness of .070. Because the silicone attaches itself to the textile, there is no separation, and no flow of air or liquids through KoolMat. The silicone offers a great resistance to abrasion, radiant heat, gasses and oils. No matter what the temperature is. It is also an excellent sound deadening device. KoolMat is flexible and can be die-cut to any shape or size and still perform like no other barrier. KoolMat is able to withstand 500° F of radiant heat and up to 2000° F with a ceramic backing. Used in 8O% of NASCAR and accepted by NHRA in October 1994.
