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 °C (-67 to +554 °F), with occasional short time exposure to 315 °C (599 °F), but usage is not limited to such applications. Each application should be considered individually.
