Title (EN) THERMOPLASTIC POLYESTER ELASTOMER RESIN COMPOSITION, AND MOLDED FOAM BODY THEREOF
(FR) COMPOSITION DE RÉSINE ÉLASTOMÈRE DE TYPE POLYESTER THERMOPLASTIQUE, ET OBJET EXPANSÉ MOULÉ EN CETTE DERNIÈRE
(JA) 熱可塑性ポリエステルエラストマー樹脂組成物およびその発泡成形体
Abstract:
(EN) Provided is a thermoplastic polyester elastomer resin composition for foam molding, which contains 0.05-9.5 parts by mass of a crystal nucleating agent (B) and 0-4.5 parts by mass of a thickening agent (C) relative to 100 parts by mass of a thermoplastic polyester elastomer (A) in which a hard segment comprising a polyester containing an aromatic dicarboxylic acid and an aliphatic and/or alicyclic diol as constituent components is bonded to at least one type of soft segment selected from among an aliphatic polyether, an aliphatic polyester and an aliphatic polycarbonate. The content of soft segments in the thermoplastic polyester elastomer (A) is 45-90 mass%, and the crystal nucleating agent (B) is an alkali metal salt of an organic carboxylic acid having 3-40 carbon atoms. The composition is suitable for forming a polyester elastomer molded foam body which is lightweight, exhibits high resilience and flexibility, and has a uniform foamed state despite having a high expansion ratio.
(FR) L'invention concerne une composition de résine élastomère du type polyester thermoplastique pour moulage de mousse, qui contient 0,05 à 9,5 parties en masse d'un agent de nucléation cristalline (B), et 0 à 4,5 parties en masse d'un agent épaississant (C), pour 100 parties en masse d'un élastomère de polyester thermoplastique (A) dans lequel un segment dur comprenant un polyester contenant un acide dicarboxylique aromatique et un diol aliphatique et/ou alicyclique en tant que constituants est collé à au moins un type de segment mou choisi parmi un polyéther aliphatique, un polyester aliphatique et un polycarbonate aliphatique. La teneur de l'élastomère de polyester thermoplastique (A) en les segments mous est de 45 à 90 % en masse, et l'agent de nucléation cristalline (B) est un sel d'un métal alcalin d'un acide carboxylique organique ayant 3 à 40 atomes de carbone. La composition convient à la formation d'un objet expansé moulé en un élastomère de polyester, qui est léger, présente une grande élasticité et une grande souplesse, et présente un état de mousse uniforme malgré un taux d'expansion élevé.
(JA) 芳香族ジカルボン酸と脂肪族及び/又は脂環族ジオールとを構成成分とするポリエステルからなるハードセグメントと、脂肪族ポリエーテル、脂肪族ポリエステル、及び脂肪族ポリカーボネートから選ばれる少なくとも1種のソフトセグメントが結合した熱可塑性ポリエステルエラストマー(A)100質量部に対して、結晶核剤(B)0.05~9.5質量部、及び増粘剤(C)0~4.5質量部の割合で含有し、前記熱可塑性ポリエステルエラストマー(A)のソフトセグメントの含有量が45~90質量%であり、前記結晶核剤(B)が炭素数3~40の有機カルボン酸アルカリ金属塩である、軽量かつ高い反発性と柔軟性を発現し、高い発泡倍率にもかかわらず均一な発泡状態を有するポリエステルエラストマー発泡成形体の成形に適した、発泡成形用熱可塑性ポリエステルエラストマー樹脂組成物である。
