A method of compounding thermoplastic polymeric material and fillers, including additives and agents, and unique compounded products. The compounding method comprises mixing the thermoplastic polymeric material in particulate form with particulate filler, and in progressive sequence melting the surface portion of the thermoplastic particles, blending the filler with said molten surface portion of the thermoplastic particles and removing the resultant blended melt and filler from the surface of the thermoplastic particles. The mixing and melting, and the blending and removing, are continued until the filler is substantially assimilated into the polymeric material and the thermoplastic particles become substantially diminished by melting and blending, or the method can be carried further if desired. The compounded product thus prepared is characterized by a distinctive stratified consistency.
