POLYARYLENE SULFIDE RESIN COMPOSITION FOR OPTICAL COMMUNICATION PART

摘要

A polyarylene sulfide resin composition for optical communication parts which comprises (A) a polyarylene sulfide resin having a melt viscosity as measured at 300 DEG C and a shear rate of 500 /sec of 8 to 20 Pa•s and (B) spherical silica which has an average particle diameter of 3 to 25 mu m and up to 50 % of which is accounted for by silica particles having a particle diameter of 1 mu m or smaller, the content of the ingredient (A) being 15 to 20 wt.%, excluding 20 wt.%, and that of ingredient (B) being 80 to 85 wt.%, excluding 80 wt.%, based on the sum of the ingredients (A) and (B). The polyphenylene sulfide resin composition is suitable for forming optical communication parts such as an optical-fiber connector ferrule and sleeve.
