Teknor Color Now Supplies Bio-Based Concentrates for the Plastics Industry's Biodegradable Resins

With the recent development of color concentrates for use with PHBV bioplastics, Teknor Color Co. now provides fully bio-based colorants for the four most widely processed bio- and petrochemical-based biodegradable resins, the company announced today.

Each of the concentrate series is now in commercial use, is classified as a bio-based material in accordance with ASTM D6866, and meets ASTM D6400 requirements for composting in an aerobic facility.

The Teknor Color bio-based product range includes concentrates with four different carrier polymers that are compatible, respectively, with these four biodegradable resin families:

  • PHBV. The newest series of color concentrates developed by Teknor Color Company were formulated for this subclass of the polyhydroxyalkanoate (PHA) bioplastic family. PHBV is polyhydroxyl butyrate / valerate.
  • PHB. In 2009, Teknor Color collaborated with Telles to develop color concentrates for use with that company's MirelTM PHB (polyhydroxyl butyrate) bioplastics, part of the PHA class.
  • PLA. Teknor Color introduced concentrates for use with polylactic acid bioplastics in 2008 and has since supplied colorants for a wide range of PLA applications.
  • PBAT. For use with this petrochemical-based biodegradable copolyester, Teknor Color now offers concentrates with either bio-based or petrochemical-based carrier resins.
