FFKM -perfluoroelastomer

Features: Exceptional resistance to degradation by fluids or gases. It resists attack by nearly all chemical reagents and provides long-term service where corrosive additives can cause other elastomers to swell or degrade. In addition, FFKM parts are less likely to cold flow than Teflon seals.

Application: Seals for use in the chemical and petroleum industries as well as for the manufacturing of semiconductors and analytical and process instruments. It is also used for high temperature applications and for paint and coating operations.

Temperature Range : Standard Compound: -13° to +600°F.

ASTM D1418 Designation : FFKM
