Expanded PTFE Gasket
Expanded PTFE Gaket is made of virgin PTFE to which a stress resistance has been added by means of molecular rearrangement during manufacture. 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 .
Expanded PTFE Gasket is 100% PTFE, resistant to all corrosive media. Soft, twistable and bendable at will.
This soft flexible gasket and sealing material easily conforms to sealing surface imperfections with less torque than conventional materials. Expanded PTFE resists cold flow and creep while offering the widest range of sealibility, chemical resistance, and temperature service of any material offered.
Expanded PTFE Gasketmaterial designed for use in process piping and equipment in chemical, pulp and paper, food and beverage and other general industrial applications where resistance to highly aggressive chemicals is required.
Expanded PTFE gasket is suitable for use in steel flanges and flanges with irregular surfaces. Expanded PTFE gasket conforms to FDA requirements.
