Abstract:
Provided are a tetrafluoroethylene copolymers having a melting point of at least 317°C, a melt flow index (MFI) at 372°C and a 5 kg load (MFI 372/5) of from about 0.60 g/10 min up to about 15 g/10 min. Also provided are methods of forming a shaped article using the copolymers described above, shaped articles made with those copolymers and compositions containing such copolymers.
