Corrosion Inhibiting Rubber Seals 770174

A new oil seal rubber compound has been developed with considerably improved GMRP corrosion rating. This was achieved by compounding the basic Hycar 1042 elastomer with compatible corrosion inhibitor, capable of inhibiting the corrosion process on rubber-metal interface. The inhibitor was compounded at 5% by weight level, and was found protective to steel, aluminum, brass and bronze. High degree of protection was achieved under increased temperature and humidity conditions, and promising results obtained in various test fluids including common oils and fuels.
