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

The semiconductor industry is a specialty market that requires seals to work in extreme chemical and temperature environments - and these seals must block materials from entering the fluid stream.
There are several different ways for seals to accomplish this task, but the first consideration is the operating characteristics.
