Trelleborg Sealing Solutions' new Isolast J9876 perfluoroelastomer is claimed to provide the most comprehensive media resistance at elevated temperatures of any perfluoroelastomer on the market. The seal material has a continuous operating temperature range from -7°C to + 275°C with occasional peaks up to +315°C. Specifically developed to cover applications in mixed chemical streams, including acids, bases, amines, steam, ethylene and propylene oxides, the material’s media resistance at high temperatures means it has excellent long-term physical property retention. The compound is available in all O-Ring sizes, as gaskets, moulded parts or rubber-to-metal bonded components, including door and gate seals.
