PFAS Classification Threatens Fluoroelastomer Supply
PFAS is a generic term referring to a group compounds that contain Carbon-to-Fluorine bonds, C-F3 and C-F21. This includes all fluoropolymers and fluoroelastomers such as FKM, FFKM, PTFE, and many others. These materials are extremely useful in critical applications due to their properties such as resistance to heat, chemicals, and environmental exposure. These important characteristics result from the strong bond between the
