ABSTRACT:
A plastic formulation is disclosed suitable for the manufacture of tile and the like. The formulation comprises an intimate mixture of a plasticized resin and a low density organic fibrous filler. The plastic formulation also comprises, in uniform dispersion, from 20 percent to 50 percent by weight of a particulate filler such as calcium carbonate, having a particle size of no more than 20 microns and from 20 to 60 percent by weight of particulate filler of a particle size between about 20 and about 200 mesh. This combination of coarse and fine particulate filler facilitates the uniform dispersion of the organic, fibrous filler.
