Fluorocarbon Rubber (FKM Rubber) is a specialized compound with excellent high heat, oil resistance and low compression set.
Fluorocarbon rubber has excellent abrasion resistance and the ability to hold a seal under hard vacuum. Gas permeability is very low and similar to that of butyl rubber.
A service life upwards of 392° F for and repeated thermal cycling makes this an ideal sealing material for aviation engine components. Generally, fluorocarbon elastomers can be custom manufactured for applications in the transportation, aerospace, and petrochemical industries.
Fluorocarbon elastomers are not suitable where low temperature flexibility is required. Vulnerable to exposure with ketones, amines, esters and alkali.
