Fluoroelastomer Compounds (FKM/FPM)

Outstanding resistance to heat, weather, ozone, oxygen and oxidisers. Very low gas permeability. PPE FKM (FPM) compounds include copolymer, terpolymer and tetrapolymer grades and bisphenol and peroxide cure systems.

The background to the text in this table is a guide to the colour. It is not an exact colour match.

To help you decide, the compounds normally most suitable for GENERAL PURPOSE use are highlighted in bold print. These are 'Standard grades'.
