The first step is the right material. But we can imagine you also need the material to have the right color, preferably with a masterbatch (colorant) which has been made with the same high standards and biodegrability as the raw material. Here we can help you as well. Masterbatches have been a Helian Polymers specialty for decades now and we apply this knowledge to develop custom masterbatches for PHA and PHBV. This way your products look the way you want to and remain sustainable.
