Kaxite expanded PTFE gasket is virgin PTFE to which a stress resistance has been added by means of molecular rearrangement during manufacturing. This process ensures that the molecular chains from which the PTFE is constructed,do not arrange themselves into set patterns.This means that expanded PTFE possesses no structural weakness (grain) and expands and contracts equally in all directions. Because no additives are required,expanded PTFE also possesses the unique chemical resistance of virgin PTFE .
