  • Comminuted styrene acrylonitrile (SAN) for use as an anti-slip or abrasive grit, texturizer, and filler, and method of making the same
    Patent number: 5567520
    Abstract: A light weight resinous plastic co-polymer comprised of styrene and acrylonitrile is ground to various sizes, especially 20 mesh and 40 mesh, and is used as an anti-slip grit, as a texturizer, and/or as a filler in coatings and plastic resins. The co-polymer, having a specific gravity of around 1.08 (water=1.0), is dispersed in or broadcast upon a liquid resin or resin system. The co-polymer disperses clear and stays suspended without adjustment or with minor adjustments to the colloidal matrix of the system.

  • Insulating and filler material comprising cellulose fibers and clay, and method of making same from paper-making waste
    Patent number: 4356060
    Abstract: A soft fluffy light weight substance comprising cellulose fibers and clay suitable as a filler and insulatng material, which is dispersible and absorbent in oil but which is not dispersible or absorbable in water, is made from paper making sludge by heating the sludge with mechanical agitation at about 350.degree. F. to evaporate all water therefrom and convert the product to lipophilic granules which are then milled in a hammer mill and forced through a screen of 3/64-5/64 inch mesh.
