Celanese/Dupont Vamac® AEM Vamac® ULTRA HT Ethylene acrylic elastomers

Vamac® Ultra HT has been developed to extend heat resistance and the dynamic performance of the standard Vamac® portfolio to a temperature range of 170 -180 °C, suitable for demanding applications such as turbo hoses and air ducts. Vamac® G has been widely used for a number of years in turbo charger hose applications. Vamac® GXF was developed to improve heat resistance and dynamic properties and these properties have now been further enhanced with the development of Vamac® Ultra HT (high temperature). 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 condensate resistance, characteristic of blow by gas, and exhaust gas recirculation. The Vamac® Ultra family which includes Vamac® Ultra HT offers a specific polymer design with a higher viscosity improving process & properties versus standard Vamac® grades. Vamac® Ultra HT can be compounded as a DOTG-free compound similar to other Vamac® terpolymer products.
