POLYARYLENE SULFIDE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a resin composition giving a resin having high rigidity, high modulus of elasticity and fluidity and alleviated coefficient of linear expansion in the thickness direction of molding product and anisotropy shrinkage percentage. SOLUTION: This polyarylene sulfide resin composition is obtained by compounding (A) 100 pts.wt. of a polyarylent suifide resin composition with (B) 5-200 pts.wt. of sericite and (C) 10-500 pts.wt. of an inorganic filler. In this case, the properties of (B) sericite have 20-55μm average flake diameter and 20-60 aspect ratio. (C) The inorganic filler is composed of a fibrous filler and a powdery filler in the weight ratio of the fibrous filler/the powdery filler of 40-80/60-20.
