  • Patent number: 5244942
    Abstract: The invention concerns a homogenous, in particular multicolored plastic sheet or panel, based on ethylene vinyl acetate copolymer (EVA) as binder with a filler content of 30 to 80 wt. % and a process for producing it. In other embodiments the binder contains, in addition to the 70 to 85 wt. % of EVA, polypropylenes to improve the processability (tendency to adhere), EPDM to improve the flexibility, and polyethylenes to reduce the tendency to soiling. In the process described, several additives, each consisting of a binder containing at least some ethylene vinyl acetate copolymer, up to 80 wt. % of fillers and up to 5 wt. % of pigments, are mixed, plasticized and granulated or comminuted to form granules or chips of assorted colours which are mixed and, possibly after other processing operations, pressed to form the plastic web or plates.
