Title:
MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2019/189316
Kind Code:
A1
Abstract:
Provided is a molded article having exceptional mechanical strength and heat resistance. A molded article containing crystals of a fluoropolymer, wherein the molded article is characterized in that: the fluoropolymer is at least one selected from the group consisting of vinylidene fluoride/tetrafluoroethylene copolymers, polychlorotrifluoroethylene, ethylene/tetrafluoroethylene copolymers, tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymers, and tetrafluoroethylene/hexafluoropropylene copolymers; and the crystals are nano-oriented crystals that are 300 nm or less in size.
