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.
Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
