Abstract

See full text

A polyester elastomer resin composition for resin belt materials contains 80-92.99% by weight of a thermoplastic polyester elastomer (A), 7-19.99% by weight of glass fibers (B) and 0.01-5.0% by weight of a crystal nucleator (C), and which is also characterized in that: the thermoplastic polyester elastomer (A) is a polyester block copolymer which contains 40-70% by weight of a high melting point crystalline polymer segment (a1) that is composed of a crystalline aromatic polyester unit and 30-60% by weight of a low melting point polymer segment (a2) that is composed of an aliphatic polyether unit; and the melt flow rate as determined in accordance with ASTM D1238 at 230° C. under a load of 2,160 g is 1.0 g/10 min or more but less than 10.0 g/10 min.
