The primary component of sealing products or rubber products made from perfluorinated sealing rubber materials is perflurane rubber, often known as FFKM.
It is a considerably better sealing material than regular FKM rubber, both in terms of material application and cost.
Purple rubber sealing material is corrosion and high temperature resistant (can resist more than 1600 different types of chemical corrosion) and they can be formed into things like gaskets, O-rings, and superior wear resistance components.
