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.

Vamac? Ultra HT provides better compound properties and higher heat resistance over Vamac? GXF as follows:
?    Higher elongation at break before and after heat ageing
?    Higher tear resistance
?    Very low hardness and modulus change after heat ageing
?    Better flex fatigue resistance after ageing.
?    170 – 180 °C continuous temperature resistance on hoses (with Nomex? textile reinforcement)

These properties make Vamac? Ultra HT the product of choice for turbo charger hoses in the 170 °C- 180 °C temperature range.
