DuPont Performance Polymers developed Vamac Ultra HT to extend heat resistance and the dynamic performance of the standard Vamac portfolio to a temperature range of 170-180°C (338-356°F), suitable for demanding applications such as turbo hoses and air ducts. Vamac Ultra HT is a terpolymer of ethylene methyl acrylate (AEM) with an acidic cure site using a diamine-based vulcanization system delivering higher mechanical properties and better low temperature flexibility. Inherently, it has a halogen-free structure like other Vamac grades, all providing superior acid resistance (acid presents in blow-by gas, and exhaust gas recirculation).
