  • Enhanced processability and properties: WACKER presents latest VINNEX grades at K2016


    As October draws near, K fever is gradually taking over in the news in the industry. More and more companies are putting out releases detailing what visitors to Europe’s biggest trade show for the plastics and rubber industry can expect to see when the show finally opens in Dusseldorf.

    Wacker, the Munich-based chemical group, has announced it will be introducing a number of novel VINNEX polymer grades for bioplastic compounds at the upcoming 20th edition of the show, which runs from October 19 to 26, 2016.

    Vinnex paprikaAccording to the company, the new additives can considerably enhance the processing and property profile of biopolyesters or blends with starch. For example, VINNEX 2526 greatly simplifies the manufacture of highly transparent, rigid polylactic acid (PLA) films. The VINNEX 2522, 2523 and 2525 products significantly improve processing and heat-sealing properties in paper coating with PLA or PBS (polybutylene succinate). VINNEX 8880 optimizes the flow properties in the melt for injection- molding applications and 3D printing, so that temperature sensitive and complex items can also readily be produced and energy can even be saved during processing.

    The polyvinyl-acetate-based grades of Wacker’s VINNEX product line now make the production of highly transparent, biodegradable PLA and/or PBS films better and easier. The addition of VINNEX 2526, for example, optimizes both melt and bubble stability during the respective extrusion processes. Blister packs can be produced at lower temperatures and with a more uniform thickness distribution. Moreover, VINNEX further enhances the already good printability of biopolyester films. In paper cups with PLA or PBS, the additive optimizes the water-repellent coating, so that the cups are in no way inferior to their polyethylene-film counterparts. During processing, the low-molecular VINNEX 2523 and VINNEX 2522 grades increase the initial adhesion of the PLA film to paper. In addition, Wacker’s additives improve the heat-sealing properties, so that a particularly strong bond forms between the paper and PLA.

    With the aid of certain VINNEX grades, film-coated paper cups can also be more readily composted and recycled– making them a more sustainable end product despite their single use. The Wacker additives can optimize items produced by injection molding or 3D printing, too. New VINNEX 8880 enhances the flow properties of the polymer melt, for example. Since this lowers the viscosity, heat-sensitive or highly complex items can also be manufactured. At the same time, more fillers – such as cellulose fibers, starch or inorganic fillers – can be incorporated into the melt.
    Wacker can be found in Hall 6, Booth A10.
