摘要

PROBLEM TO BE SOLVED: To provide thermoplastic polyester resin foam particles having an excellent expandability and capable of manufacturing a foam molding excellent in terms of heat resistance, buffering capacity, and mechanical strengths.;SOLUTION: The thermoplastic polyester resin foam particles of the present invention are thermoplastic polyester resin foam particles used for intra-mold foam molding applications and include not only 100 pts.wt. of a non-crystalline thermoplastic polyester resin including, as a diol component, at least one type selected from the group consisting of 1,4-cyclohexanedimethanol, 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and spiroglycol and having a glass transition point (Tg) of 100 to 130°C but also 10-900 pts.wt. of a crystalline thermoplastic polyester resin having a specific viscosity of 0.8-1.1.;COPYRIGHT: (C)2014,JPO&INPIT
