Title (EN) LIQUID-CRYSTALLINE RESIN COMPOSITION AND INSERT-MOLDED ARTICLE
(FR) COMPOSITION DE RÉSINE CRISTALLINE - LIQUIDE ET ARTICLE MOULÉ PAR INSERTION
(JA) 液晶性樹脂組成物及びインサート成形品
Abstract:
(EN) [Problem] To provide: a liquid-crystalline resin composition which is capable of giving insert-molded articles having excellent airtightness; and an insert-molded article which includes a resin member comprising the liquid-crystalline resin composition . [Solution] The above-mentioned problem is solved with a liquid-crystalline resin composition which comprises a liquid-crystalline resin, a thermoplastic resin having a glass transition temperature Tg lower than 230ºC, and a platy filler having an average particle diameter of 15-100 µm and an aspect ratio of 10 or higher, wherein the content of the liquid-crystalline resin is 40-65 mass% of the whole resin composition, the content of the thermoplastic resin is 12-35 mass% of the whole resin composition, and the content of the platy filler is 10-35 mass% of the whole resin composition.
(FR) Le problème posé est de produire une composition de résine cristalline-liquide qui permet de donner des articles moulés par insertion ayant une excellente étanchéité à l'air; et un article moulé par insertion qui comprend un élément de résine comprenant la composition de résine cristalline-liquide. [Solution] Le problème précité est résolu au moyen d'une composition de résine cristalline-liquide qui comprend une résine cristalline-liquide, une résine thermoplastique ayant une température de transition vitreuse Tg inférieure à 230 °C, et une charge lamellaire ayant un diamètre de particule moyen de 15 à 100 µm et un rapport de forme égal ou supérieur à 10, la teneur de la résine cristalline-liquide étant comprise entre 40 et 65 % en masse de la totalité de la composition de résine, la teneur en résine thermoplastique étant comprise entre 12 et 35 % en masse de la totalité de la composition de résine, et la teneur de la charge lamellaire étant comprise entre 10 et 35 % en masse de la totalité de la composition de résine.
(JA) 【課題】気密性に優れるインサート成形品を得ることができる液晶性樹脂組成物、及びその液晶性樹脂組成物からなる樹脂部材を有するインサート成形品を提供する。 【解決手段】液晶性樹脂と、ガラス転移温度Tgが230℃未満である熱可塑性樹脂と、平均粒径が15μm以上100μm以下でありアスペクト比が10以上である板状充填剤と、を含有し、液晶性樹脂の含有量が、全樹脂組成物中40質量%以上65質量%以下であり、熱可塑性樹脂の含有量が、全樹脂組成物中12質量%以上35質量%以下であり、及び、板状充填剤の含有量が、全樹脂組成物中10質量%以上35質量%以下である液晶性樹脂組成物により上記課題を解決する。
