WACKER is one of the world’s leading and most research-intensive chemical companies, with total sales of 4,69€ billion (2020). As a committed partner to the plastics industry, WACKER’s carbon- and silicon-based additives help to unleash the potential of biodegradable plastics.
The novelty of the additives is their synergistic effects
which have recently been discovered. With such unique combinations, biodegradable plastics can be processed like standard thermoplastics on conventional plastic-processing machinery, while the mechanical and surface properties are sufficiently improved. Carbon-based VINNEX® additives act as compatibilizers for different biopolyesters and fillers, and improve the final material’s flexibility, softness, impact resistance and processing. VINNEX® lowers the viscosity of the melt, but also increases the melt strength at the same time. Silicone-based GENIOPLAST® additives impart a lower extruder torque, lower die pressure and higher throughput. They improve the final material’s surface properties, such as lower coefficient of friction, better scratch resistance and better soft touch.
