Silicone Elastomers For Automotive Application

Wacker India, a subsidiary of Wacker Chemie AG, offers ready-to-use silicone elastomers that also finds use in the automotive and transportation industry. The products include ELASTOSIL R plus 48xx and ELASTOSIL LR 384x. These are oil-bleeding silicones that are used for manufacturing electrical mat seals and weather packs for automotive electronics. ELASTOSIL R plus 48xx is a one-part, solid silicone rubber with excellent mechanical properties. It features extremely high tear strength and elongation, and is ideal for seals that must be especially cut resistant. Mat seals and cable bushing mats made from ELASTOSIL R plus 48xx are so cut resistant that they are not damaged even when sharp-edged plugs are inserted. ELASTOSIL R plus 48xx is an addition-curing product and cures much faster than a peroxide-curing silicone. Consequently, production cycles can be shortened dramatically. Injection moulded, thermal post-curing of the resultant elastomer imbues it with low, permanent compression set and therefore with good long-term sealing action. The ELASTOSIL LR 384x is a liquid silicone rubber with a broad processing window. It tolerates fluctuating process parameters, perfectly moulded parts are obtained even if process temperatures, pressures and injection profiles are not accurately maintained. ELASTOSIL LR 384x is available in different shore hardness values, and oil contents of 1 to 6 per cent. It is injection moulded like standard liquid silicones. The end products do not require thermal post-curing as they achieve low, permanent compression set and thus provide good long-term sealing action without additional curing.
