Excellent resistance to aggressive automotive fluids including biofuels, E85, and modern low-SAPS engine oils.
Outstanding high-temperature performance with continuous service capability up to 200 °C.
Superior resistance to swelling and degradation in exposure to aromatic hydrocarbons and polar solvents.
Good processability for compression, transfer, and injection molding operations.
Low compression set retention after prolonged thermal aging, ensuring long-term sealing integrity.
Fuel system components: O-rings, gaskets, and diaphragms for direct fuel contact.
Under-hood sealing solutions: Valve cover gaskets, turbocharger hoses, and coolant expansion tank seals.
Chemical processing equipment: Linings, diaphragms, and pump seals exposed to harsh process media.
Aerospace fluid systems: Seals for hydraulic, fuel, and lubrication lines requiring FAA-compliant materials.
Oil & gas downhole tools: Elastomeric elements subjected to sour gas (H₂S), CO₂, and high-temperature hydrocarbons.
