Perfluoroelastomers (FFKM)
Perfluoroelastomers (FFKM) Materials
A Top Choice for Harsh Chemical Environments
Perfluoroelastomers (FFKM) are often known by trade names, including Kalrez®, Simriz®, Chemraz®. All perfluoroelastomers offer the ultimate chemical resistance for sealing applications, particularly in harsh environments. They are commonly used to produce O-rings in applications that will put the material in contact with highly corrosive fluids or a wide range of temperatures. These compounds are designed to provide superior chemical resistance, as well as thermal stability for your sealing needs.

The Benefits of Perfluoroelastomers
Resistance to High Temperatures and Chemicals
Perfluoroelastomers, as we noted, offer high chemical resistance but they also provide decent resistance to both cold and hot temperatures. The material can seal at temperatures as low as 0°F to -15°F (-18°C to -26°C) and as high as 450°F to 600°F (232°C to 316°C). They also offer resistance to the following:
- Aliphatic and aromatic hydrocarbons
- Chlorinated hydrocarbons
- Polar solvents
- Inorganic and organic acids
- Water
- Steam
The material is not compatible with alkali metals and should not be used in medical applications.
