Abstract
(EN)
Disclosed is a thermoplastic elastomer composition comprising a blend of at least two fluoropolymers. The first fluoropolymer has from 0 to 30 weight percent of a monomer J selected from the group consisting of hexafluoropropene (HFP), fluorinated or perfluorinated vinyl ethers, 2,3,3,3-tetrafluoropropene, trifluoropropene, 1-chloro-3,3,3-trifluoro propene or combinations thereof. The second fluoropolymer has at least 30 weight percent, preferably at least 35 weight percent, of monomer T selected from the group consisting of hexafluoropropene (HFP), fluorinated or perfluorinated vinyl ethers, 2,3,3,3-tetrafluoropropene, trifluoropropene, 1-chloro-3,3,3-trifluoro propene or combinations thereof.
