Additives for Biopolymers
From compostable packaging to biodegradable plastic cutlery, biopolymers are on the rise. The only limits are technical performance and processability. VINNEX® is a polyvinyl acetate-based additive that allows the combination of several biopolymers, thereby improving performance and processability. With VINNEX®, biopolymers can be processed just like standard thermoplastics. The system makes materials such as starch, polylactic acid (PLA), polyhydroxyalkanoates (PHA), polybutylene succinate (PBS) and cellulose acetates (CA) compatible with each other. This makes it possible to precisely adjust the physical properties as required, while maintaining the biodegradability of the biopolymer blends. In addition, most VINNEX® grades are suitable for use in food-contact applications.
Silicone-based GENIOPLAST® additives enhance the processing and material properties of biopolymers.
