Abstract: front page image
(EN)The invention pertains to a thermoplastic fluoropolymer composition comprising: - at least one semi-crystalline polymer comprising recurring units derived from ethylene and at least one of chlorotrifluoroethylene (CTFE) and tetrafluoroethylene (TFE), said polymer having a heat of fusion of at most 35 J/g [polymer (A)]; and - from 0.05 to 5 % by weight, based on weight of polymer (A), of particles of at least one inorganic UV blocker compound, said particles having an average particle size of 1 to 150 nm, said composition being suitable for manufacturing UV-opaque films having outstanding transparency and haze properties.
(FR)L'invention concerne une composition de fluoropolymère thermoplastique comprenant: - au moins un polymère semi-cristallin comprenant des unités de répétition dérivées d'éthylène et du chlorotrifluoroéthylène (CTFE) et/ou du tétrafluoroéthylène (TFE), ledit polymère ayant une chaleur de fusion de 35 J/g au maximum [polymère (A)] ; et - de 0,05 à 5 % en poids, par rapport au poids de polymère (A), de particules d'au moins un composé inorganique empêchant le passage des ultraviolets, lesdites particules ayant une taille moyenne de particule de 1 à 150 nm, ladite composition pouvant être utilisée pour la fabrication de films opaques aux ultraviolets ayant des propriétés exceptionnelles de transparence et de voile.
