Self-adhesive liquid silicone rubber with low-friction surfaces
Wacker Chemie
Among other products, this company will be showcasing its portfolio of self-adhesive liquid silicone rubbers with low coefficients of friction. The portfolio comprises two new product lines: Elastosil LR 3671 for applications in food technology and Elastosil LR 3675 for automotive applications. It will also present Silpuran 6760/50, a grade dedicated to medical applications with comparable surface properties. All three products are self-adhesive to metals and selected thermoplastics. When cured, they form elastomers with dry, low-friction surfaces (photo), enabling cost-effective large-scale production of injection-molded hard/soft composites. Silicone elastomers made from these products have coefficients of friction that are 50 to 70% lower than those of comparable standard silicone rubber, says the company. The friction-lowering effect is achieved without exuding oil, as happens in oil-bleeding silicone elastomers. That makes the products ideal for use in the manufacture of components with low-friction surfaces that must be kept oil-free. Hall 6, Stand A10 — Wacker Chemie AG, Munich, Germany
