We are a professional manufacturer specializing in fluoropolymer materials and tubing products.
FKM (Fluoroelastomer) is a premium fluorinated synthetic rubber known for its exceptional chemical resistance, high-temperature stability, and mechanical durability. It is widely used in demanding sealing applications such as O-rings, gaskets, and hoses, especially in automotive, aerospace, chemical processing, and oil & gas industries.
Temperature Resistance: Continuous use from -20°C to +250°C (short-term up to 300°C).
Chemical Resistance: Resistant to fuels, oils, acids, alkalis, and most aggressive solvents.
Weatherability: Excellent resistance to ozone, UV, and aging.
Mechanical Performance: High tensile strength, compression set resistance, and sealing performance.
Low Permeability: Superior barrier properties against gases and fluids.
Automotive Industry: O-rings, oil seals, fuel hoses, gaskets for engines and transmissions.
Aerospace: Seals and gaskets in hydraulic systems, fuel systems, and high-temperature environments.
Chemical & Energy: Seals for pumps, valves, tanks, and chemical processing equipment.
Electronics & Semiconductor: Chemical-resistant seals for wet processes.
Industrial Machinery: High-performance sealing parts exposed to aggressive fluids and high heat.
Q1: What is the difference between FKM and Viton?
A1: Viton™ is a well-known brand of FKM produced by Chemours. FKM is the general name for fluoroelastomers.
Q2: What temperatures can FKM withstand?
A2: FKM typically operates from -20°C to +250°C, with short-term exposure up to 300°C.
Q3: Is FKM suitable for contact with fuels and oils?
A3: Yes, FKM has excellent resistance to oils, fuels, and aggressive automotive fluids.
Q4: Can FKM be used in food or medical applications?
A4: Standard FKM is not food grade, but special formulations (FDA-compliant grades) are available.
Q5: How does FKM compare with silicone or NBR rubber?
A5: FKM offers higher heat and chemical resistance than NBR or silicone, making it the best choice for harsh environments.
