PTFE

Virgin - Unfilled P.T.F.E. is the most common form and has some unique features which, apart from its good slip characteristics, the advantages of this high performance product lies less in its mechanical than in its thermal, electrica.

POLYTETRAFLUOROETHYLENE (PTFE) exhibits a unique set of characteristics and is resistant to practically all chemicals. An excellent construction material, it will not degrade when exposed to UV or swell and dissolve in common organic or inorganic solvents. It has a low co-efficient of friction with a wide service temperature range and unless chemically treated, no substance will stick to the non-stick surface of PTFE.

 

FEATURES

APPLICATIONS
