Title (EN) OPTICALLY CLEAR UV AND HYDROLYSIS RESISTANT POLYESTER FILM
(FR) FILM DE POLYESTER OPTIQUEMENT TRANSPARENT ET RÉSISTANT AUX UV ET À L'HYDROLYSE
Abstract: front page image
(EN)Biaxially oriented polyester films including polyester polymer, a carbodiimide hydrolysis stabilizer, and a UV absorber are described. The polyester films have a carboxyl end group concentration of 5-20 equivalents per ton, and a haze value of 2% or less. The films exhibit superior transparency and possess stable light transmission characteristics. Methods of making the films and articles produced from the films are also described.
(FR)L'invention porte sur des films de polyester à double orientation qui comprennent un polymère polyester, un stabilisant de l'hydrolyse carbodiimide et un absorbeur d'UV. Les films de polyester ont une concentration en groupes terminaux carboxyles de 5 à 20 équivalents par tonne et ont une valeur de trouble inférieure ou égale à 2 %. Les films présentent une transparence supérieure et possèdent des caractéristiques de transmission de lumière stables. L'invention porte également sur des procédés de fabrication des films et sur des articles fabriqués avec ces films.
