Patent ID: 8586677

Claim:
A fluoropolymer composition, comprising: at least one high molecular weight polytetrafluoroethylene which has been trace modified with a modifying co-monomer (TMHPTFE) and having a number average molecular weight (M n ) of at least 500,000 and a first melt temperature (Tm) of less than 342° C., said modifying co-monomer present in an amount of less than 1 wt. %, based on the weight of said TMHPTFE, said at least one TMHPTFE present in an amount of between 50 wt. % and 90 wt. % based on the total solids weight of all fluoropolymers in said composition; at least one melt-processible fluoropolymer (MPF) selected from perfluoroalkoxy (PFA) and methylflouroalkoxy (MFA), said MPF present in an amount of between 10 wt. % and 50 wt. % based on the total solids weight of all fluoropolymers in said composition, and having a melt flow index (MFI) greater than 10 g/10 min; and wherein said composition lacks low molecular weight polytetrafluoroethylene (LPTFE) having a number average molecular weight (M n ) of less than 500,000.
