This specification covers a fiberglass reinforced silicone rubber in the form of sheet, strip, and molded parts.These products have been used typically for grommets or anti-chafing cushions between metal surfaces operating at temperatures between -55 to +290 \mDC (-67 to +554 \mDF), with occasional short time exposure to 315 \mDC (599 \mDF), but usage is not limited to such applications. Each application should be considered individually.
