Homogeneous, in particular multicolored structured plastic sheets or sheets based on ethylene-vinyl acetate copolymer (EVA) as binders with filler contents of 35 to 80% by weight and a process for their production are described. In further embodiments of the invention, in addition to 70 to 85% by weight EVA, the binder also contains proportions of polypropylene to improve processability (tendency to stick), EPDM to improve flexibility and polyethylene to reduce soiling. According to the process described, several batches, each consisting of a binder which contains at least a proportion of ethylene-vinyl acetate copolymer, as well as up to 80% by weight of fillers and up to 5% by weight of color component, are mixed, plasticized and granulated or Crushing into granules or chips of different colors, which are mixed together and, if necessary, processed. after further process steps - are pressed to the plastic sheets or sheets. |
