What is FMK?
FKM, also known as fluoroelastomer, is a synthetic rubber that contains fluorine. It has excellent resistance to heat, chemicals, and oils, making it ideal for high-performance applications. FKM is a copolymer of vinylidene fluoride (VDF) and hexafluoropropylene (HFP) monomers, and it is classified into two types, including FKM terpolymer and FKM copolymer.
What does Terpolymer mean?
Terpolymer is a type of polymer that contains three different monomers. In the case of FKM terpolymer, it contains VDF, HFP, and tetrafluoroethylene (TFE). The presence of TFE in the FKM terpolymer provides it with improved chemical resistance and low-temperature flexibility compared to FKM copolymer.
Physical and Mechanical properties
FKM terpolymer has excellent physical and mechanical properties that make it suitable for various industrial applications. It has high tensile strength, elongation at break, and tear resistance. FKM terpolymer also has good compression set and abrasion resistance. The material is available in a range of hardness levels, from 60 to 90 Shore A.
Chemical and Temperature Resistance
FKM terpolymer has excellent chemical resistance and can withstand a wide range of chemicals, including acids, alkalis, and oils. The material is also resistant to high temperatures and can operate continuously at temperatures up to 200°C. FKM terpolymer can withstand intermittent exposure to temperatures up to 260°C.
FKM Terpolymer Cured: Applications
FKM terpolymer cured is widely used in various applications, including seals, gaskets, O-rings, hoses, and other products that require high-performance materials.
