Companies in the plastic’s industry continues to look for color concentrate solutions to meet sustainability goals. To support these customers Chroma Color’s technical team continues to develop additional options. Recently, a customer was looking for a partner to come up with a color masterbatch using a PHA (polyhydroxyalkanoates) biobased polyester that would comply to *ASTM D-6400/*DIN EN13432 Bio-Composting standards.
The Chroma Color Technology team developed three new colors for our customer using a specifically designed carrier resin for a masterbatch:
41OR0001SC41CO-F Orange 50/1
41RD0001SC41CO-F Red 50/1
41WH000141CO-F White 50/1
*ASTM D6400 outlines the standard requirements for the biodegradation of solid materials through composting, specifically tailored for labeling plastics intended for aerobic composting in municipal or industrial settings.
*DIN EN 13432 specifies the requirements and procedures for determining the compostability and aerobic treatability of packaging (and its materials).
About PHA’s: are a family of biobased and biodegradable polyesters made by bacterial fermentation. PHACT biopolymers were chosen for this project are plant-based and feature a sustainable manufacturing process. Alone or when blended with other polymers, they dramatically improve environmental characteristics while enhancing physical properties in a broad range of consumer applications. This material is considered to be thermally stable in the normal and customary processing range of 185- 200 Cº. Extended polymer and concentrate residence time in the process equipment may require that process temperature profiles be reviewed and/or adjusted to insure a proper and suitable product.
