Abstract
Provided are a polyarylene sulfide resin composition and its moldings of good mold releasability, good heat resistance and good surface smoothness. Coated with a metal film, the moldings may be lamp reflectors of good image reflection. The resin composition comprises (A) a polyarylene sulfide resin having a melt viscosity of from 100 to 1,500 poises at 300° C. in terms of the resin temperature and at a shear rate of 200 sec−1, (B) an inorganic granular filler having a volume-average particle size of at most 4 μm, (C) whiskers having a fiber diameter of at most 7 μm, and (D) a metal salt of a fatty acid having from 26 to 30 carbon atoms.
Claims6
A polyarylene sulfide resin composition comprising (A) 100 parts by weight of a polyarylene sulfide resin having a melt viscosity of from 100 to 1,500 poises at 300° C. in terms of the resin temperature and at a shear rate of 200 sec−1, (B) from 20 to 250 parts by weight of an inorganic granular filler having a volume-average particle size of at most 4 μm, (C) from 0 to 50 parts by weight of whiskers having a fiber diameter of at most 7 μm, provided that the total of the components (B) and (C) is at most 250 parts by weight, and (D) from 0.1 to 5 parts by weight of a metal salt of a fatty acid having from 26 to 30 carbon atoms.
