Polyester type resin constituent null polyethylene terephthalate

摘要

PROBLEM TO BE SOLVED: To provide a polyester-based resin composition for engine peripheral parts which is excellent in moldability, impact resistance, lightness, heat resistance and sound insulating properties and can be molded into engine peripheral parts hardly causing thermal discoloration and dimensional change due to water absorption. ;SOLUTION: When a polyester-based resin composition comprises (A) 60-92 wt.% polyethylene terephthalate-based polymer, (B) 5-15 wt.% talc and (C) 3-25 wt.% polyolefin-based polymer, this polyester-based resin composition features having a flexural breaking strain of ≥3.5% and a deflection temperature under load of ≥180°C.;COPYRIGHT: (C)2001,JPO
