Melt-processible Poly(tetrafluoroethylene)

A melt-processable fluoropolymer,

• the fluoropolymer being a copolymer of tetrafluoroethylene and one or more comonomers;
• said one or more co-monomers being present in less than 1 mol %;
• the fluoropolymer having
• a crystalline melting temperature of about 320° C.;
• a stress at break of greater than 15 MPa (at room temperature and a strain rate of 100% min);
• a crystallinity in the range of 5 to 60% (based on a value of 102.1 J/g for 100% crystalline PTFE);
• and
• a melt-flow index (according to ASTM D 1238-88 at 380° C. under a 21.6 kg load) of greater than 0.25 g/10 min, and less than 75 g/10 min.
