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
