Title (EN) POLYCARBONATE RESIN COMPOSITION AND FORMED ARTICLE
(FR) COMPOSITION DE RÉSINE POLYCARBONATE ET ARTICLE MIS EN FORME
Abstract:
(EN) Provided is a formed article produced by forming a polycarbonate resin composition, wherein the polycarbonate resin composition contains a polycarbonate resin and silica fine particles having an average primary particle size of 0.5 nm or more and 30 nm or less; in the polycarbonate resin composition, a content of the silica fine particles with respect to a total amount of the polycarbonate resin and the silica fine particles is 40 vol% or more and 80 vol% or less; and the formed article has, in a range of 20°C to 60°C, a linear expansion coefficient that is 20 x10-6/°C or less and may be a negative value.
(FR) La présente invention a pour objet un article mis en forme produit par la formation d'une composition de résine polycarbonate, la composition de résine polycarbonate contenant une résine polycarbonate et de fines particules de silice ayant une taille de particule primaire moyenne de 0,5 nm ou plus et de 30 nm ou moins ; dans la composition de résine polycarbonate, une teneur des fines particules de silice par rapport à une quantité totale de la résine polycarbonate et des fines particules de silice étant de 40 % en volume ou plus et de 80 % en volume ou moins ; et l'article mis en forme possédant, dans une gamme allant de 20 °C à 60 °C, un coefficient d'expansion linéaire qui est de 20 x 10-6/°C ou moins et peut être une valeur négative.
