Vamac® ethylene acrylic elastomer
Vamac® (AEM) products are a comprehensive family of heat and fluid resistant elastomers for flexible applications ranging from hoses, dampers and boots to seals and gaskets. Vamac® provides significant performance advantages over low temperature ACM and HNBR grades, including better low temperature resistance and high temperature performance up to 175°C. Compared to HNBR substantial cost savings can be achieved.
Flame resistance / Smoke suppression / Corrosive off-gases
Vamac® is not inherently flame-resistant. However, it can be filled easily with large volumes of hydrated alumina. This polymer/ filler combination provides vulcanizates with good flame resistance, off-gases free of halogens, and an unusually low smoke density. The heat aging performance associated with normal compounds of Vamac® will be reduced by the necessarily high levels of alumina in low-smoke, "reduced fire hazard", compositions. Magnesium hydroxide may also be used, but only in Vamac® dipolymer. The choice of flame retardant filler is critical; metal oxides, for example, will ionically cross-link Vamac® terpolymers.
Compounds of Vamac® resist oil better than compounds of Neoprene or silicone. The oil resistance of Vamac® approaches that of acrylonitrile and epichlorohydrin, but is less than that of Viton®. see chart appendixed below*
