PFOA-free FKM is a type of fluoroelastomer material that is manufactured without the use of perfluorooctanoic acid (PFOA), a potentially harmful chemical. PFOA is a synthetic compound that has been used in the production of various fluoropolymer materials, including some types of FKM elastomers, as a surfactant and processing aid.

PFOA-free FKM is typically manufactured using alternative surfactants and processing aids that do not contain PFOA. These materials are designed to maintain the same properties and performance characteristics as traditional FKM materials, while reducing the potential health and environmental risks associated with PFOA.
