Performance
Outstanding Oil and Fuel Resistance: Excellent compatibility with mineral oils, synthetic lubricants, diesel, gasoline, and biofuels, maintaining sealing integrity in fluid handling systems.
Wide Temperature Resistance: Operates reliably from -40°C to 180°C (short-term peak up to 200°C), suitable for high-temperature engine and industrial environments.
Excellent Mechanical Properties: High tensile strength, tear resistance, and abrasion resistance, ensuring long service life even under dynamic operating conditions.
Low Compression Set: Minimal permanent deformation after prolonged compression, providing consistent sealing pressure over extended periods.
Resistance to Aging: Good resistance to ozone, weathering, and oxidation, preventing premature degradation in outdoor and harsh operating environments.
Application
Automotive Industry: Seals for engine fuel systems, oil pans, transmission systems, and turbocharger hoses, withstanding exposure to fuels and high temperatures.
Hydraulic and Pneumatic Systems: Dynamic seals for hydraulic cylinders, valves, and pumps, providing leak-proof performance under high pressure.
Oil and Gas Industry: Downhole sealing components, wellhead equipment seals, and pipeline gaskets, resistant to crude oil and drilling fluids.
Industrial Machinery: Seals for compressors, gearboxes, and injection molding machines, suitable for high-temperature and heavy-duty operating conditions.
Aerospace: Sealing components for aircraft hydraulic systems and fuel lines, meeting strict performance and safety standards
