Title:
フッ素樹脂成形方法及びフッ素樹脂成形品
Document Type and Number:
Japanese Patent JP5542295
Kind Code:
B2
Abstract:
A fluoropolymer molding method and the resulting molded article are disclosed where the fluoropolymer is composed of fluoropolymer particles each having a multi-layer structure that consists of at least two types of fluoropolymers having different melting points, with at least one inner layer made of a fluoropolymer with a melting point higher than that of the outermost fluoropolymer. The fluoropolymer of the at least one inner layer is molded at a temperature higher than the melting point of the lowest melting point of the fluoropolymers that form the outermost layers of the multi-layer-structure fluoropolymer particles, and lower than the melting point of the fluoropolymer having the highest melting point. The resulting articles have excellent chemical liquid resistance and gas impermeability and low linear expansion coefficient.
