POLYARYLENE SULFIDE RESIN POWDER/GRAIN COMPOSITION AND METHOD FOR PRODUCING SAME

摘要

The purpose of the present invention is to efficiently provide a polyarylene sulfide resin powder/grain composition having a small average particle diameter, excellent powder fluidability and a low compression degree. A polyarylene sulfide resin powder/grain composition comprising: 100 parts by weight of a powdery or granular polyarylene sulfide resin having an average particle diameter of more than 1 µm and up to 100 µm and a uniformity degree of 4 or less; and 0.1 to 5 parts by weight of inorganic fine particles having an average particle diameter of 20 to 500 nm inclusive.
