The present invention relates to a filler masterbatch composition comprised of a polymer selected from an impact polypropylene, a high density polyethylene, and a polyolefin elastomer and a mineral filler and a filled thermoplastic composition produced by combining such a filer masterbatch composition with a polymer. The inventive filler masterbatch allows for a higher compounding rate, better dispersion, and elimination of a typical compounding step in the production of filled thermoplastic compositions.
