Abstract:
A shaped article comprising a mixture of thermoplastic PFA fluoropolymers consisting essentially of units of tetrafluoroethylene, from 0.5 to 10 mol % of units of one or more perfluoro alkyl vinyl ethers having from 1 to 4 carbon atoms in the perfluoroalkyl radical and up to about 5 mol % of other fluoromonomers not containing hydrogen, the mixture comprising:at least 10% by weight of the mixture and not more than 90% by weight of the mixture of at least one component A) with a melt flow index (MFIA)&gE;30 g/10 min. and not more than 90% by weight of the mixture and at least 10% by weight of the mixture of at least one component B) with a melt flow index (MFIB)&lE;15 g/10 min., the components being selected in such a way that the ratio of MFIA to MFIB is in the range from 80 to 2500.
