Abstract:
A fluorine containing thermoplastic vulcanizate composition comprising a continuous phase of at least one uncured melt formable thermoplastic resin and a blend of at least two cured fluorine containing elastomers where one of the elastomers is a vinylidene fluoride/tetrafluoroethylene/propylene terpolymer,wherein the vinylidene fluoride/tetrafluoroethylene/propylene terpolymer comprises between 5 and 95 weight percent of the total dispersed elastomer phase, and the total dispersed elastomer phase comprises from between 40 and 90 weight percent based on the total amount of the continuous phase and the dispersed phase combined, and, the dispersed elastomer phase is not formed from monomer constituents comprised of special cure site monomers.
