POLYARYLENE SULFIDE RESIN COMPOSITION FOR OPTICAL COMMUNICATION PART

摘要

The invention is drawn to a polyarylene sulfide resin composition for optical communications parts, containing a polyarylene sulfide resin (A) having a melt viscosity of 8 to 20 Pa.s as measured at 300 DEG C and a shear rate of 500/sec and spherical silica (B) having a mean particle size of 3 to 25 mu m and containing silica particles having a particle size of 1 mu m or less in an amount of 50 wt.% or less based on the entire amount of the silica, the component (A) content being 15 wt.% or more and less than 20 wt.% and the component (B) content being more than 80 wt.% and 85 wt.% or less, based on the sum of the weights of the components (A) and (B). According to the invention, a polyphenylene sulfide resin composition suitably used for forming optical communications parts such as optical fiber connector ferrules and sleeves can be provided.
