The present invention relates to the field of processing thermoplastic polymers, particularly the present invention relates to a process for manufacturing compacted material suitable for the use in thermoplastic polymers without a compounding step, comprising the steps of a) providing at least one primary powder material; b) providing at least one molten surface treatment polymer; c) simultaneously or subsequently feeding the at least one primary powder material and the at least one molten surface treatment polymer into the high speed mixer unit of a cylindrical treatment chamber; d) mixing the at least one primary powder material and the at least one molten surface treatment polymer in the high speed mixer, e) transferring the mixed material obtained from step d) to a cooling unit, as well as the compacted material obtained by this process and its use in thermoplastic polymers.

Process for manufacturing a surface-treated compacted material processable on a single screw plastics conversion equipment

The present invention relates to a composition, comprising (i) a polypropylene having a melt flow index MFI(230&#xb0; C., 2.16 kg) of less than 2.0 g/10 min, a flexural modulus of from 1200 to 2400 MPa, a density of from 0.895 to 0.910 g/cm, (ii) a high-density polyethylene, and (iii) an inorganic filler.
