PROBLEM TO BE SOLVED: To obtain a polyphenylene sulfide resin composition enabling burr to be decreased, and useful for various kinds of electric and electronic parts, especially small precision parts or the like by adding a specific amount of a colloidal silica to a polyphenylene sulfide resin. SOLUTION: This polyphenylene sulfide resin composition is obtained by adding (B) a colloidal silica to (A) a polyphenylene sulfide resin. Preferably, the amount of the added component B is 0.0005-0.5 pts.wt. expressed in terms of silica based on 100 pts.wt. component A, and the particle diameter of the silica in the component B is 1-60 nm. Especially, the silica is the one having a string-like shape with 1-60 nm thickness and 10-500 nm length. The composition preferably contains (C) 0.05-5 pts.wt. alkoxysilane compound having a functional group such as an epoxy group based on 100 pts.wt. component A. |
