  • Patent number: 7999022
    Abstract: Polymer slurries of ultrahigh molecular weight polyalpha-olefins are made stable toward settling, separation and agglomeration by surface treatment with a combination of wax and optional relatively high-density particulates. The selection of the surface coating acts not only as an anti-blocking agent, or partitioning aid to keep the tacky polymer particles separated, but also provides the suspended polymer particle with a density that matches the carrier. This prevents separation of the slurry components over time. Such materials, ultimately used as pipeline additives to reduce the fluid drag and increase the volumetric throughput, can be stored and shipped for extended periods of time without degradation of the slurry quality. Upon injection into the pipeline, the polymer particle dissolves quickly, unhindered by the coating.

  • Patent number: 7745011
    Abstract: A low-cost and effective coating composition for cardboard allows use of thinner paper board with the same or higher strength relative to conventional water-resistant cardboard. The resulting cardboard can also be repulped and more easily recycled. The inventive coating composition, preferably applied to the fluted inner ply of the cardboard (as a waterproof barrier), is compatible with the utilization of low-cost starch-based adhesives for gluing the fluting to the liners. At least one side of the fluting cardboard is coated with a composition comprising: from about 10% to 70% by weight, and more preferably from about 40% to 60% by weight, of sodium silicate; from about 10% to 60% by weight, and more preferably from about 30% to about 50% by weight, of a synthetic resin emulsion; from about 10% to 50% of a paraffin-water emulsion; and from about 5% to about 25% by weight of added water.

    Abstract: A method for packaging plastic material using a film to surround the material, and more particularly to a method for packaging hot melt adhesives, the resulting package formed thereby, and the film composition used therein. The method is preferably a coextrusion process for packaging a pressure sensitive hot melt adhesive by extruding a hot melt adhesive through a die orifice, and coextruding a wax-based polymeric film to surround the hot melt adhesive. The coated adhesive may then be formed into individual packaged units having a finite size and shape. The polymeric film comprises a composition having at least 25% by weight of a wax material, an enthalpy of fusion of at least about 100 J/g, and an elongation value at break of at least about 100%. Any type of hot melt adhesive formulation can be packaged or surrounded by the polymeric film in the process.
