Document Type and Number:
WIPO Patent Application WO/2010/122915
Kind Code:
A1
Abstract:
Disclosed is a polybutylene terephthalate resin material which has excellent durability under temperature cycle conditions, while maintaining high welding strength when the integration is carried out by heat welding. Specifically disclosed is a polybutylene terephthalate resin composition for welding, which is obtained by blending, per 100 parts by weight of (A) a polybutylene terephthalate resin having a terminal carboxyl group amount of not more than 30 meq/kg, (B) a carbodiimide compound in such an amount that the carbodiimide functional group amount is equal to 0.3-1.5 equivalent when the terminal carboxyl group amount of the polybutylene terephthalate resin is taken as 1 equivalent, and (C) 0-15 parts by weight of an elastomer.
