Polyvinyl acetate-based additive system are used for compatibilizing different biopolymers with one another, so allowing a new generation of bioplastics to be formulated, also it simplifies processing by traditional methods.
Main Features and Advantages
PVAC, VAE and hybrids of homo-, co- or terpolymers of vinyl acetate makes materials such as starch, polylactic acid (PLA), polyhydroxyalkanoates (PHA), polybutylene succinate (PBS) and cellulose acetates (CA) compatible with one another. This allows the formulator to adjust the physical properties precisely according to requirements.
Improved Physical Properties
Depending on the amount and type PVAC/VAE added, the polymer blends have higher impact strengths and better melt stability or are more flexible than the pure biopolymers.
- No Limitations on the Main Features such as compostability
- Most grades are suitable for use in food-contact applications.
- Easy processing makes injection molding, extrusion, vacuum forming, thermoforming and calendering much easier.
