Trelleborg Sealing Solutions” Isolast J9876 is a perfluoroelastomer that is designed to provide exceptional media resistance at elevated temperatures. Seals in this material enable extended life in aggressive high-temperature environments and an optimized cost to performance ratio, meaning the compound can be specified over a range of applications. Isolast J9876 has a continuous operating temperature range from +19 F to +527 F/ -7 C to + 275 C with occasional peaks up to +599 F / +315 C. The material’s media resistance at high temperatures means long-term physical property retention. The compound is available in any size o-ring, gasket, molded part or rubber-to-metal bonded components, including door and gate seals. It is suitable for mechanical seals, chemical processing systems, pumps, valves, power generation equipment, refineries and semiconductor applications not directly exposed to plasma sources.
