5 - 7 weight in the polybutyrene terephthalate resin (A)100

摘要

PROBLEM TO BE SOLVED: To provide an automotive wire harness connector, hardly causing cracking or chipping in spite of a thin-wall part of ≤0.35mm thickness possessed thereby, good in impact resistance and excellent in various characteristics required for products, e.g. the holding power for electrodes and strength after heat treatment and wet heat treatment. ;SOLUTION: This automotive wire harness connector made of a polyester resin is composed of a resin composition prepared by adding (B) 0.05-1 pt.wt. hindered phenolic compound and/or (C) 0.05-1 pt.wt. thiophenolic compound to (A) 100 pts.wt. polybutylene terephthalate(PBT) resin containing 3-7wt.% polytetramethylene glycol having 500-3,500 molecular weight as a copolymerization component. The wire harness connector has a thin-wall part of ≤0.35mm thickness.;COPYRIGHT: (C)1998,JPO
