Estimating the term…
A process for transforming a polymer base, having a shaded appearance of anisotropic coloring, into a finished article, the process including operations of mixing a base polymer and additives, of adding a shading colorant to the polymer mixture, followed by incomplete homogenization of the shading colorant in the polymer mixture to form the polymer base with a shaded appearance of anisotropic coloring, subsequent shaping to an intermediate predetermined shape, and vulcanization and cooling as applicable, and then an operation of breaking up the shaded polymer base into individualized elements and an operation of aggregation of the elements, to obtain the finished article, in any desired arrangement. It also relates to a finished article, having such anisotropy, constituted by an agglomerate of individualized elements, and its application as a surface coating.
