Elastosil LR 3011/50 FR and Elastosil LR 3170/40
Previous liquid silicone rubbers owed their flame retardancy to inert fillers such as quartz, which caused abrasion during the injection molding process. In contrast, Elastosil LR 3011/50 FR and Elastosil LR 3170/40 are formulated with inert fillers that contain no abrasive additives. Because they exhibit considerably less abrasive behavior during injection molding, maintenance needs are reduced and the useful life of the mold is extended. The self-adhesive Elastosil LR 3170/40 is designed for two-component injection-molded products, as the liquid silicone rubber begins bonding with hard components (but not to the surface of the injection mold) during the vulcanization process. Both grades have received the best flammability rating (V-0) available under the Underwriters Laboratories Standard UL 94.

Vinnapas EP 1400
Vinnapas EP 1400 is a high-performance base polymer characterized by high setting speed and good machine properties. This aqueous copolymer dispersion, based on vinyl acetate and ethylene (VAE), is designed for adhesives for the paper and packing, laminating, and product-assembly industries. The VAE technology makes it possible for users to simplify adhesive formulations using fewer additives, thereby reducing costs. With a glass-transition temperature of 0_C, the material also provides fast film formation, high setting speed, good machine processability, and excellent mechanical properties. It is produced without using alkylphenol ethoxylates, has a low formaldehyde content (<10 ppm), and makes it possible to formulate adhesives with a low content of volatile organic compounds.
