Abstract: Thermoplastic compositions include from about 40 wt % to about 90 wt % of a crystalline polymer, from about 5 wt % to about 50 wt % basalt fibers, and from about 1 wt % to about 20 wt % of an impact modifier. In some aspects the crystalline polymer includes polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), copolymers thereof, or a combination thereof. The thermoplastic compositions are suitable for use in nano molding technology (NMT) applications, and in particular for consumer electronics applications.
