Abstract:
(EN) Provided is a modified PTFE having exceptional heat resistance. A modified polytetrafluoroethylene that contains a polymer having a unit based on tetrafluoroethylene and a polymer having a unit based on a non-fluorine monomer, wherein the modified polytetrafluoroethylene is such that an endothermic ratio R calculated by a prescribed method is 0.65 or higher.
(FR) L’invention concerne un polytétrafluoroéthylène (PTFE) modifié, excellent en matière de résistance à la chaleur. Ce polytétrafluoroéthylène modifié contient un polymère possédant une unité à base de tétrafluoroéthylène, et un polymère possédant une unité à base de monomère non fluoré, et le rapport (R) de valeur endothermique de ce polytétrafluoroéthylène, calculé à l’aide d’un procédé prédéterminé, est supérieur ou égal à 0,65.
(JA) 耐熱性に優れる変性PTFEの提供。 テトラフルオロエチレンに基づく単位を有する重合体と、非フッ素系単量体に基づく単位を有する重合体と、を含む変性ポリテトラフルオロエチレンであって、所定の方法で算出される吸熱量比Rが0.65以上である、変性ポリテトラフルオロエチレン。
