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°C. 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.
