摘要：
The present invention refers to a surface treated filler material product comprising a) at least one calcium carbonate-containing filler material and b) a treatment layer on the surface of the at least one calcium carbonate-containing filler material comprising i. maleic anhydride grafted polyethylene and/or maleic anhydride grafted polypropylene and ii. at least one hydrophobizing agent. Furthermore, a process for preparing the inventive surface treated filler material product is disclosed, as well as a polymer composition comprising at least one polymeric resin and the inventive surface treated filler material product. Additionally, a fiber and/or filament and/or film and/or thread and/or sheet and/or pipe and/or profile and/or mold and/or, injection molded compound and/or blow molded compound comprising the inventive surface treated filler material product is disclosed as well as the use of the inventive surface treated mineral filler product in a polymer composition, for improving the mechanical and/or rheological properties of the polymer composition.
