Polyarylene sulfide resin composition for optical telecommunication members

摘要

Provided is a polyarylene sulfide (PAS) resin composition having extremely high dimensional accuracy and favorable to fiber-optics connector members, etc. The PAS resin composition for optical telecommunication members comprises (A) from 20 to 35% by weight of a polyarylene sulfide having a crystallization temperature, as measured through differential scanning calorimetry, of not lower than 250° C., and (B) from 65 to 80% by weight of silica, preferably spherical silica having a mean particle size of from 1 to 10 mum.
