Performance
Extreme Temperature Resistance: Operates stably from -20°C to 220°C (short-term up to 250°C).
Excellent Chemical Compatibility: Resists fuels, oils, lubricants, hydraulic fluids, acids, and many solvents.
Low Compression Set: Maintains sealing integrity under long-term compression with minimal permanent deformation.
High Pressure Resistance: Performs reliably in both static and dynamic high-pressure hydraulic/pneumatic systems.
Aging, Ozone & UV Resistance: Excellent weatherability prevents cracking and degradation over extended service life.
Low Permeability: Minimizes gas and fluid leakage in critical sealing applications.
Application
· Automotive & Transportation: Engine seals, fuel system O-rings, transmission seals, turbocharger systems.
· Hydraulic & Pneumatic Systems: Valves, pumps, cylinders, connectors, and fluid power equipment.
· Oil & Gas Industry: Downhole tools, pipeline seals, drilling equipment, and chemical processing systems.
· Aerospace & Aviation: Aircraft hydraulic systems, engine components, avionics sealing.
· Industrial Machinery: Pumps, compressors, heat exchangers, and heavy-duty manufacturing equipment.
· Chemical Processing: Seals for reactors, pipelines, and storage systems handling aggressive media.
