Title (EN) FLUORORESIN MOLDED BODY
(FR) CORPS MOULÉ EN RÉSINE FLUORÉE
(JA) フッ素樹脂成形体
Abstract:
(EN) The present invention relates to: a PFA molded body comprising a copolymer (PFA) of tetrafluoroethylene (TFE) and perfluoro(alkyl vinyl ether) (PAVE), with the content of PAVE being 1 to 10 mol%, characterized by having a flex life value of 2,000,000 or more, a zero shear viscosity of 10,000 to 20,000 Pa∙s, and a thermogravimetric weight loss of 0.05 weight% or less; and a method for producing the same. This PFA molded body has a high flex life value, a low heated weight loss value, and a low zero shear viscosity while maintaining excellent mechanical properties such as tensile strength and is capable of being produced at high yields.
(FR) La présente invention concerne : un corps moulé en PFA comprenant un copolymère (PFA) de tétrafluoroéthylène (TFE) et de perfluoro(alkylvinyléther) (PAVE), la teneur en PAVE étant de 1 à 10 % en mole, caractérisé en ce qu'il présente une résistance à la flexion alternée de 2.000.000 ou plus, une viscosité à cisaillement nul de 10.000 à 20.000 Pa∙s et une perte de poids thermogravimétrique de 0,05 % en poids ou moins ; et un procédé pour sa production. Ce corps moulé en PFA présente une résistance à la flexion alternée élevée, une faible valeur de perte de poids chauffée et une viscosité à cisaillement nul basse, tout en conservant d'excellentes propriétés mécaniques telles qu'une résistance à la traction et peut être produit à des rendements élevés.
(JA) 本発明は、テトラフルオロエチレン(TFE)とパーフルオロ(アルキルビニルエーテル)(PAVE)との共重合体(PFA)で、PAVEの含有量が1~10モル%である共重合体(PFA)からなり、フレックスライフ値が2,000,000回以上であり、ゼロシェア粘度が10,000~20,000Pa・sであり、かつ熱重量減が0.05重量%以下であることを特徴とするPFA成形体及びその製造方法に関する。このPFA成形体は、優れた引張強度等の機械的物性を維持しながら、高いフレックスライフ値、低い加熱重量減値を有すると共に、ゼロシェア粘度が低く、成形体を生産性良く製造することができる。
