Cao su FKM (Fluoro Elastomers)
FKMs (sometimes known as FPMs) are frequently used to resist extreme temperatures and harsh chemicals. The strong carbon-fluorine bonds that make up the polymer structure provide high thermo-chemical resistance, giving excellent ageing characteristics shown by low compression set at elevated temperatures.
FKMs offer excellent resistance to mineral oils and greases, aliphatic, aromatic and some chlorinated hydrocarbons, petrol and diesel fuels, silicone oils and greases. However FKMs show poor resistance to ethers, esters and amines.
FKMs are available as a copolymer (two monomers), terpolymer (three monomers) or as a tetra polymer (four monomers). Each type determines both fluorine content and chemical structure which in turn significantly impact the chemical resistance and temperature performance of the polymer.
More recent innovations include the development of FKM materials for use in low temperature applications, where with a glass transition of -40°C, it is possible to use FKMs down to -51°C in service.
Fluoro elastomers are fluorine-containing polymers noted for their exceptional resistance to heat, weathering and a wide assortment of fluids and chemicals, as well as for their exceptional sealing and mechanical properties. The working temperature range for Fluoro elastomers is considered to be –26°C to 205-230°C, but for short working periods they will take even higher temperatures. Some per fluorocarbon elastomer types can resist temperatures up to 327°C. Products that contain Fluoro elastomers, for example certain O-rings, gaskets and hoses, are essential for industries such as automotive, aerospace and others. Fluoro elastomers are used mainly in seals and barrier layers subjected to environments too severe for other elastomers.
