Perlast® G70A uses a unique molecular cross-linking technology to offer the broadest range of chemical resistance of any FFKM with the ability to operate up to a maximum temperature of 260°C (500°F). An extremely versatile material, Perlast® G70A is suitable for 90% of sealing applications encountered in the chemical processing and refining industries, providing excellent resistance to highly aggressive acids, amines, chlorine and solvent-based chemistries. Perlast® G70A is available as fully moulded O-rings (any size up to 2m/6.5ft internal diameter), custom shapes and profiles. Key Attributes Ultimate chemical resistance to a wide range of chemicals Exceptional acid and amine resistance Excellent steam resistance Superior mechanical properties High sealing efficiency Typical Applications Pumps Valves Mechanical seals Compressors (high H2S concentration environments) Pressure vessels Diesel engines (pre-chambers and exhaust systems) Couplings & Fittings Custom shapes and profiles
