According to Intech, DuPont's Tefzel product line was never discontinued, just referred to as ETFE (Ethylene Tetrafluoroethylene) Teflon.

 

In 2013, DuPont expanded the product line by developing a powder primer (532-6405) and a new high build clear topcoat (532-6410) to complement the existing Tefzel products.  The new high build product can be applied to film builds of 80-100 mils, depending upon part geometry. 

 

Tefzel is a rugged thermoplastic with an outstanding balance of properties.  When compared against the competition, Tefzel® provides several thermal advantages, such as: better chemical resistance at higher operating temperatures, a higher melting point which provides improved thermal stability, and lessened low temperature embrittlement.

 

In addition to these qualities, Tefzel s extremely tough and electrically insulative with superior substrate adhesion.
