GENIOPLAST® Pellet 345 complements WACKER’s portfolio of silicone-based additives for the compounding of thermoplastic polymers. The product has been specifically developed with thermoplastic polyurethanes (TPUs) in mind, but can be used for modifying other thermoplastic elastomers as well. For example, the product, which is supplied in pellet form, can markedly boost the properties of thermoplastic polyamide and copolyester elastomers.
GENIOPLAST® Pellet 345 is a silicone copolymer and is processed like a thermoplastic. Organic polymer segments contained within GENIOPLAST® Pellet 345 make it so compatible with thermoplastic polyurethanes that, unlike conventional silicones, it disperses very finely and homogeneously throughout the polyurethane matrix. The copolymer becomes physically bound to the matrix and is therefore unable to migrate. In Europe, GENIOPLAST® Pellet 345 is authorized for food-contact applications.
Adding GENIOPLAST® Pellet 345 boosts the surface smoothness of thermoplastic polyurethanes, thereby enhancing their scratch and abrasion resistance. Moreover, surfaces become more resistant to contamination by foodstuffs and cosmetics. These effects are achieved at additions of just 3 to 5 percent.
