Title (EN) METHOD FOR PRODUCING POLYTETRAFLUOROETHYLENE MOLDED ARTICLE
(FR) PROCÉDÉ DE PRODUCTION D'UN ARTICLE MOULÉ EN POLYTÉTRAFLUOROÉTHYLÈNE
(JA) ポリテトラフルオロエチレン成形品の製造方法
Abstract: front page image
(EN)Disclosed is a method for producing a PTFE molded article, which enables to make the thickness of a PTFE molded article extremely thin, while having an extremely low extrusion pressure during extrusion molding. Specifically disclosed is a method for producing a polytetrafluoroethylene molded article, which is characterized by comprising a step for extrusion molding a dispersion liquid of primary particles of polytetrafluoroethylene.
(FR)La présente invention concerne un procédé de production d'un article moulé en PTFE, permettant de rendre l'article moulé en PTFE extrêmement mince, tout en ayant une pression d'extrusion extrêmement faible pendant le moulage par extrusion. L'invention concerne de manière spécifique un procédé de production d'un article moulé en polytétrafluoroéthylène, caractérisé en ce qu'il comprend une étape de moulage par extrusion d'un liquide de dispersion de particules primaires de polytétrafluoroéthylène.
(JA)本発明は、PTFE成形品のPTFEの厚みを極めて薄くすることができ、押出成形時の押出圧力が極めて小さいPTFE成形品の製造方法を提供する。 本発明は、ポリテトラフルオロエチレンの1次粒子の分散液の押出成形を行う工程を含むことを特徴とするポリテトラフルオロエチレン成形品の製造方法である。
