PURPOSE: A polyarylene sulfide resin composition is provided which has excellent dimensional stability and abrasion resistance. More specifically, the polyarylene sulfide resin composition maintains strength by adding a fibrous filler such as glass fiber or carbon fiber to a polyarylene sulfide, reduces anisotropy of coefficient of linear expansion by adding calcium carbonate as an inorganic filler, and obtain improved abrasion resistance by adding potassium titanate as other inorganic filler. CONSTITUTION: A polyarylene sulfide resin composition essentially comprises 30 - 60 parts by weight of a polyarylene sulfide, 10 - 30 parts by weight of a fibrous filler, 20 - 30 parts by weight of calcium carbonate, 10 - 30 parts by weight of potassium titanate and 5 - 15 parts by weight of a polytetrafluoroethylene. |
