Title (EN) RESIN COMPOSITION, MOLDED ARTICLE, AND METHOD FOR PRODUCING SAME
(FR) COMPOSITION DE RÉSINE, ARTICLE MOULÉ ET PROCÉDÉ DE PRODUCTION DUDIT ARTICLE MOULÉ

Abstract:
(EN) [Problem] To provide: a resin composition for a bump-off molded article with which it is possible to prevent deformations from remaining in a molded article after release even when released from the mold by bump-off, the resulting molded article having exceptional rigidity; a bump-off molded article in which the resin composition is used; and a method for producing the same. [Solution] A resin composition for a bump-off molded article in which the flexural modulus at 23°C is 8 GPa or higher and the flexural modulus at 150°C is less than 40% of the flexural modulus at 23°C. The flexural modulus at 150°C is preferably 5 GPa or less.
(FR) Le problème décrit par la présente invention est de fournir : une composition de résine pour un article moulé par éjection par percussion avec laquelle il est possible d'empêcher que des déformations persistent dans un article moulé après le démoulage même lorsqu'il est démoulé par éjection par percussion, l'article moulé obtenu ayant une rigidité exceptionnelle ; un article moulé par éjection par percussion dans lequel est utilisée la composition de résine ; et un procédé de production associé. La solution selon l'invention porte sur une composition de résine pour un article moulé par éjection par percussion dans laquelle le module de flexion à 23 °C est de 8 GPa ou plus et le module de flexion à 150 °C est inférieur à 40 % du module de flexion à 23 °C. le module de flexion à 150 °C est de préférence de 5 GPa ou moins.
(JA) 【課題】無理抜き方式により金型から離型させても離型後の成形品に変形が残ることを防ぐことができ、かつ得られた成形品が優れた剛性を有する無理抜き成形品用樹脂組成物、及びそれを用いた無理抜き成形品、並びにその製造方法を提供する。 【解決手段】23℃における曲げ弾性率が8GPa以上であり、150℃における曲げ弾性率が23℃における曲げ弾性率の40%未満である、無理抜き成形品用樹脂組成物とする。150℃における曲げ弾性率が5GPa以下であることが好ましい。
