  • Colorant concentrates for thermoplastic biofiber composites
    Patent number: 8501866
    Abstract: Color concentrates for thermoplastic biofiber composites are disclosed. The concentrates employ three factors to achieve concentrated delivery of color to the processing machine and excellent and substantially uniform dispersion of color in the processing machine: melt flow of the concentrate exceeding at least 4 g/10 min. using ASTM D-1238; pellet size of the concentrate such that at least 50 pellets weigh less than one gram; and weight percent of the colorant ingredients in the concentrate exceeding at least 30 weight percent.
    Type: Grant
    Filed: September 24, 2010
    Date of Patent: August 6, 2013
    Assignee: PolyOne Corporation
    Inventors: Peter Prusak, Thomas M. Majewski
  • Liquid color concentrate
    Patent number: 8252855
