Abstract
An extruded thermoplastic composition includes: (a) from about 20 wt % to about 75 wt % of a ceramic fiber component; (b) from about 15 wt % to about 70 wt % of a polybutylene terephthalate (PBT) component including a high molecular weight PBT and a low molecular weight PBT; (c) from about 5 wt % to about 23 wt % of a polycarbonate component; and (d) from about 1 wt % to about 10 wt % of a compatibilizer component. Methods of making the extruded thermoplastic composition are also described.
