What is FKM?
“FKM” stands for Fluoroelastomer, which is a type of synthetic rubber that contains fluorine atoms in its polymer structure. Fluoroelastomers are known for their exceptional resistance to a wide range of chemicals, fuels, oils, and high temperatures. They are commonly used in applications that require sealing, gaskets, and components in harsh and demanding environments.
