PROBLEM TO BE SOLVED: To aim to improve the form stability and the thermal shock resistance of molded articles which require such a form stability as housing and have a wide range of the working environmental temperature. SOLUTION: Resin compositions comprise (A) a polybutylene terephthalate, (B) glass fibers, (C) glass flakes, and (D) an ethylene/α-olefin copolymer with an amount of component (A) and component (C) to be added of (B)/(B)+(C)<=0.5 and the glass flakes (C) having a residue of sieve of not less than 90% by a sieve of nominal size of 150μm prescribed by JIS Z8801. It is preferred that, based on 100 pts.wt. polybutylene terephthalate (A), the amount of the glass fibers (B) is 10-30 pts.wt.; that of the glass flakes (C) is 10-30 pts.wt.; and that of the ethylenic copolymer (D) is 0.1-20 pts.wt. |
