Abstract
A thermoplastic composition includes from about 40 wt % to about 60 wt % polycarbonate homopolymer or copolymer, from about 15 wt % to about 30 wt % styrene acrylonitrile copolymer, from about 13 wt % to about 15 wt % flat glass fiber, and from about 9 wt % to about 11 wt % round glass fiber. Methods for making a thermoplastic composition include forming a mixture from the recited components and extruding or molding the mixture to form the composition.
