FFKM

FFKM is perflurane rubber, that is, the main material of sealing products or rubber products made of perfluorinated sealing rubber materials.Both in terms of material application and price, it is a much higher sealing material than general FKM rubber. It can be said that it is not a grade of product grade. Purple rubber sealing material can resist high temperature environment and corrosion (can resist more than 1600 kinds of chemical corrosion). They can be shaped to:
· O-rings
· Superior wear resistance
· Gaskets, etc
