Patents by Inventor Rob Hanssen

Rob Hanssen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Blended nucleating agent compositions and methods
    Patent number: 7879933
    Abstract: Certain thermoplastic additives that induce simultaneous good material properties and high nucleation efficacy are provided. Such additives include combinations of a phosphate salt and a dicarboxylate salt. This combination or blend may be provided in various ratios. A method for applying such a combination in a thermoplastic formulation is also disclosed. A thermoplastic formulation, which may or may not include polypropylene, is also disclosed in connection with the combination.
    Type: Grant
    Filed: October 14, 2008
    Date of Patent: February 1, 2011
    Assignee: Milliken & Company
    Inventor: Rob Hanssen
  • Polymer compositions comprising nucleating or clarifying agents and articles made using such compositions
    Patent number: 7786203
    Abstract: A polymer composition comprises a polyolefin and a nucleating or clarifying agent dispersed or dissolved in the polyolefin. Methods for producing the polymer composition and method for producing articles from the polymer composition are also described. Molded polymer articles and polymer film may be manufactured using the compositions of the invention.

  • Nucleating agent additive compositions and methods
    Patent number: 7659336
    Abstract: A blend of two different compounds may be applied together to form a nucleating agent additive composition. This additive composition is useful as an additive in thermoplastics, polyolefins and/or polymer resins. A blend of a bicyclo[2.2.1]heptane dicarboxylate salt and a dicarboxylate calcium metal salt provide useful and beneficial physical property effects in molded polymeric articles in terms of shrinkage and crystallization temperature of polymer resin compositions.
