Patent ID: 8329839

Claim:
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 a total amount at 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.
