(EN) CYCLOOLEFIN RESIN COMPOSITION, MOLDED ARTICLE THEREOF, AND MIRROR
(FR) COMPOSITION À BASE DE RÉSINE CYCLOOLÉFINIQUE, ARTICLE MOULÉ À BASE DE CELLE-CI ET MIROIR
Abstract
(EN)
A molded article is formed by molding a cycloolefin resin composition, in which the cycloolefin resin composition contains a cycloolefin resin and silica particles, the silica particles have an average primary particle size of 10 nm to 150 nm, the cycloolefin resin composition has a silica particle content of 15% by weight to 70% by weight, and the molded article has a linear expansion coefficient of 50 x 10-6/degrees (Celsius) or less in the temperature range of 0 degrees (Celsius) to 80 degrees (Celsius).
(FR)
Un article moulé est fabriqué par moulage d'une composition à base de résine cyclooléfinique contenant une résine cyclooléfinique et des particules de silice, lesdites particules de silice présentant une taille moyenne des particules primaires variant de 10 à 150 nm, ladite résine cyclooléfinique présentant une teneur en particules de silice variant de 15 à 70 % en poids et l'article moulé étant caractérisé par un coefficient de dilatation thermique linéaire inférieur ou égal à 50 x 10-6/degré (Celsius) dans l'intervalle de température allant de 0 à 80 degrés (Celsius).
