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 /
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.
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.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
