What is FFKM?
“FFKM” stands for Perfluoroelastomer, which is a specialized class of elastomers that offers the highest level of chemical resistance, thermal stability, and mechanical performance among elastomeric materials. Perfluoroelastomers are used in extreme environments where resistance to aggressive chemicals, high temperatures, and harsh conditions is required.
FFKM Information
Process: Injection Molding, Compression Molding
Colors: Black or brown
Tolerance: Tight tolerances
Price: Expensive
Application: semiconductor manufacturing, aerospace, chemical processing, oil and gas
Recommended Wall Thickness: 1mm-10mm or even thicker
