description A PFA molded article of a copolymer (PFA) of tetrafluoroethylene (TFE) and perfluoro(alkylvinyl ether) (PAVE), the content of the PAVE therein being from 1 to 10% by mol, characterized in that the PFA molded article has a flex life value of not less than 2,000,000 times, a zero share viscosity of from 10,000 to 20,000 Pa·s, and a heating weight loss of not more than 0.05% by weight, and a process for the production thereof. The PFA molded article has a high flex life value, a low heating weight loss and a low zero share viscosity yet maintaining excellent mechanical properties such as tensile strength, etc., and can be produced in good yields.
