FFKM Dupont® Kalrez®, Markez®, Chemraz®, Perlast®, Isolast®, Parofluor®, Perfluorelastomer
Common Names:  Perfluoroelastomers, FFKM
Trade Names: Chemraz®, Kalrez®, Markez®, Isolast®, Parofluor® , Perlast®.

General Description: Perfluoroelastomer (FFKM) is a highly fluorinated elastomeric family of compounds that provide the most resistance to chemicals and high temperature than any other elastomer in the market.   FFKMs are considered the elastomeric equivalence to PTFE (Teflon) due to its excellent chemical and temperature resistance. Features:

• Excellent chemical resistance to most chemicals.
• The highest temperature resistant elastomeric material in the market.
• Can be molded into o-rings, X-rings and a wide variety of custom shapes.
• Available in many different compound and colors targeted for specific applications and markets
• Compounds available to meet FDA, USP Class VI and Explosive Decompression Resistance requirements.

Limitations:

• Molten alkali metals
• Dynamic applications

Temperature resistance:

• -46o to 327o C (-51o to 620o F).  Depends on compound and application.
