Fluororubber (FKM/FPM) is a high-performance synthetic elastomer with fluorine atoms in its molecular structure, which can function under extreme operating conditions where standard rubber fails.
Core Advantages
Extreme Heat Resistance: Operates reliably from -20°C to +260°C (even up to 300°C for short periods), resisting thermal aging.
Superior Chemical Resistance: Withstands oils, fuels, solvents, acids, and alkalis—ideal for harsh chemical contact.
Excellent Sealing Performance: Maintains elasticity and tight seals under high pressure, preventing leakage.
