Title: FLUORINE-CONTAINING COPOLYMER COMPOSITION AND MOLDED ARTICLE
Abstract:
Provided are: a fluorine-containing copolymer composition which is capable of forming a molded article having excellent stiffness at high temperatures and having stress crack resistance at even higher temperatures; and a molded article obtained from the fluorine-containing copolymer composition. This fluorine-containing copolymer composition contains a fluorine-containing copolymer and a copper oxide, and satisfies α0 ≥ 10, 0.8 ≤ α24/α0 ≤ 1.2, and 0.8 ≤ α96/α0 ≤ 1.2, wherein the fluorine-containing copolymer is a specific ethylene/tetrafluoroethylene copolymer. In the above equations, α0 represents a volume flow rate (in g/10 minutes) of the fluorine-containing copolymer composition under a load of 49 N at 297°C, α24 represents a volume flow rate (in g/10 minutes) of the fluorine-containing copolymer composition under a load of 49 N at 297°C after being heated for 24 hours at 225°C, and α96 represents a volume flow rate (in g/10 minutes) of the fluorine-containing copolymer composition under a load of 49 N at 297°C after being heated for 96 hours at 225°C.
