Abstract:
Heat aging of the composition comprising melt-fabricable tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer, the alkyl containing 1 to 5 carbon atoms and melt flowable polytetrafluoroethylene is effective to cause thermal transformation of the composition in the solid state, which is epitaxial co-crystallization of the polymer components of the composition, and other valuable changes, such as increased continuous use temperature.
