PHA colour masterbatch

Chroma Color’s customer was looking for a partner to come up with a colour masterbatch using a PHA (polyhydroxyalkanoates) biobased polyester that would comply to *ASTM D-6400/*DIN EN13432 Bio-Composting standards.

The Chroma Color Technology team was able to develop three new colours 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

The PHACT biopolymers, developed by CJ Biomaterials, that 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. AT
