Thin-walled molded articles (i.e., molded articles where at least 70% of the wall thickness is 0.8 mm or less) are formed of a polybutylene terephthalate (PBT) molding composition having improved fluidity characteristics and desirable mechanical strength properties. The PBT molding composition includes (A) 100 parts by weight of a polybutylene terephthalate base resin having a melt index of between 40 and 200 as measured at 235.degree. C. under a load of 2160 grams according to ASTM D-1238; (B) between 1 to 60 parts by weight of plate-like glass flakes having an average flake dimension of between 10 to 200 .mu.m; and (C) between 0.01 to 5 parts by weight of a fatty acid metal salt.

Polybutylene terephthalate molding composition and molded thin-walled

A resin composition comprises a polybutylene terephthalate, a halogenated bisimide having the formula (1) and a polytetrafluoroethylene resin and is improved in flame retardancy and at the same time moulding properties. It is useful for parts of electric instruments. ##STR1##
