FKM rubber compound is a high-performance synthetic fluoroelastomer. It combines strong heat resistance with excellent resistance to oils, fuels, chemicals, and weathering. Therefore, manufacturers commonly use it for seals, O-rings, gaskets, hoses, and other demanding industrial components.
4. How is FKM rubber made?
FKM rubber is produced by polymerising fluorinated monomers to create a fluoroelastomer base polymer. Manufacturers then combine this polymer with curing agents, fillers, processing aids, and other additives to create an FKM compound with the required hardness, durability, and performance characteristics.
5. How durable is FKM rubber compound?
FKM rubber compound is highly durable, particularly in demanding environments. It offers excellent resistance to heat, oils, fuels, many chemicals, ozone, and weathering. As a result, FKM components can maintain their sealing and mechanical properties for long periods when the correct grade is selected.
6. Is FKM a natural rubber?
No, FKM compound is not natural rubber. It is a synthetic fluoroelastomer manufactured using fluorinated chemical compounds. Unlike natural rubber, FKM is specifically designed to provide superior resistance to high temperatures, oils, fuels, chemicals, ozone, and other challenging operating conditions.
7. What type of rubber is FKM elastomer?
FKM elastomer is a synthetic fluorocarbon rubber belonging to the fluoroelastomer family. It is engineered for demanding applications where conventional rubber may struggle with high temperatures, oils, fuels, and chemicals. Therefore, it is widely used in automotive, aerospace, chemical, and industrial applications.
8. What is FKM made of?
FKM elastomer is made from fluorinated monomers that form a fluorocarbon-based polymer structure. Different FKM grades use different monomer combinations to achieve specific properties. The resulting material offers excellent resistance to heat, fuels, oils, chemicals, ozone, and environmental ageing.
9. What is the hardness of FKM elastomer rubber?
The hardness of FKM elastomer can vary depending on its formulation and intended application. Commercial FKM compounds are commonly available across a broad range of Shore A hardness levels, with many sealing applications using grades around 70–90 Shore A. Manufacturers can adjust the compound to meet specific performance requirements.
