VINNEX®

VINNEX® is WACKER’s trade name for a polyvinyl acetate-based additive system for compatibilizing different biopolymers with one another, so allowing a new generation of bioplastics to be formulated. Moreover, VINNEX® simplifies processing by traditional methods.

VINNEX® Additives are homo-, co- or terpolymers of vinyl acetate. The system 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 of VINNEX® 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

The blends are just as biobased and/or biodegradable as pure biopolymers.

Suitable for food contact.

Most VINNEX® grades are suitable for use in food-contact applications.

Easy processing

With VINNEX®, biopolymers can be processed just like standard thermoplastics. VINNEX® makes injection molding, extrusion, vacuum forming, thermoforming and calendering much easier.

VINNEX® makes biopolymers more suitable - or even feasible at all - for many applications and processing technologies.

Typical applications include:

  • highly transparent PLA film with significantly improved weldability for food packaging.
  • Paper extrusion coatings with PLA for paper cups
  • Thermoforming PBS/PLA blends for heat-resistant containers
