High resistance to aggressive automotive fluids including modern low-SAPS engine oils and biofuels.
Excellent thermal stability with continuous service capability up to 200 °C in air.
Superior compression set resistance, ensuring long-term sealing performance under dynamic conditions.
Good processability on standard rubber processing equipment, including extrusion and injection molding.
Low gas permeability, especially effective for fuel and refrigerant containment applications.
Automotive fuel system components: fuel rails, injectors, and high-pressure hose linings.
Under-hood sealing solutions: valve cover gaskets, turbocharger seals, and EGR system components.
Industrial fluid handling: chemical pump diaphragms and metering valve seats.
Aerospace hydraulic and pneumatic seals requiring extended service life at elevated temperatures.
Oil & gas downhole tools and wellhead equipment exposed to sour gas (H₂S) and hydrocarbon media.
