  • Patent number: 9085681
    Abstract: A low gloss capstock compound is disclosed. The combination of gloss inhibiting agents, metal-based ionomer thermoplastic resins, and acid scavenger added to conventional polyethylene polymer resin achieves a gloss angle at 85° of below 10 GU. Optionally, the compound can also include weathering agents to improve outdoor durability. The compound can be fully formulated or a masterbatch for let-down into polymer to form the fully formulated compound.
    Type: Grant

    Date of Patent: July 21, 2015
    Assignee: PolyOne Corporation
    Inventors: Thomas Majewski, Hari Rajaraman, Roman B. Hawrylko
  • Patent number: 9085680
    Abstract: A low gloss capstock compound is disclosed. The combination of gloss inhibiting agents and polyolefin elastomer added to conventional polyethylene polymer resin achieves a gloss angle at 85° of below 10 GU. Optionally, the compound can also include weathering agents to improve outdoor durability. The compound can be fully formulated or a masterbatch for let-down into polymer to form the fully formulated compound.

  • Patent number: 8252855
    Abstract: A liquid color concentrate is disclosed, having a liquid acrylic-based polymer carrier; colorant; and optionally other functional additives. The colorant can be one or more pigments, one or more dyes, or combinations thereof. The liquid polymer is compatible with a variety of plastic resins, especially optically clear plastic resins, such as polycarbonate, polymethyl methacrylate, and styrene-acrylonitrile.

  • Patent number: 8168697
    Abstract: Coated colored biofiber for thermoplastic articles is disclosed. The coating on the biofiber comprises film-forming polymeric binder, surfactant, and colorant. The colorant can be one or more pigments, one or more dyes, or combinations thereof. The coated colored biofiber can be used in thermoplastic compounds to simulate the appearance of natural wood while adding durability.

  • Patent number: 7973099
    Abstract: A pre-processed polymer composite is disclosed comprising a heat-sensitive polymer resin particle; particles of colorant or functional additive in association with the heat-sensitive polymer resin particle; and a thermoplastic encapsulant to form a film around the associated polymer and colorant or functional additive particles. The method of making the polymer composite avoids a melting of the heat-sensitive polymer resin particles, which avoids contributing to heat history of the polymer prior to extrusion or molding into the form of the final plastic article.
