General Description : A semi-crystalline perfluorinated polymer closely related to PTFE (FP30) being a copolymer of tetrafluoroethylene and hexafluoropropylene. Its properties are similar, but generally a little inferior to, those of PTFE but it has the great practical advantage of being melt-processable (though more expensive).

Compared in more detail to PTFE, it has similarly excellent chemical resistance and electrical properties (up to very high frequencies) and good weathering resistance. It has better radiation resistance and much higher impact strength but has lower maximum use and heat deflection temperatures and is even a little less stiff and strong. Though not quite crystal clear, it is transparent (essentially from 250/300 to 7000nm) and colourless or with a slight bluish tinge.

Applications include coatings and protective linings, chemical and medical equipment, extruded insulation and glazing film for solar panels.
