Abstract
A composition of matter comprising poly(arylene sulfide), fiberglass, and calcium sulfate. A method for producing compositions that is compared with compositions outside of this invention upon molding provide improved insulation resistance and improved surface gloss by admixing calcium sulfate having an average particle size in a range of about 0.5 micron to about 5 microns with poly(arylene sulfide) and fiberglass.
