DuPont: New high-heat resistant AEM elastomers

Chart 1 (DuPont) demonstrates the improvement in long-term AEM heat resistance already available with DuPont™ Vamac® Ultra compounds, and the further step-change now achieved with the new Vamac® VMX-5000 Series of AEM pre-compounds.

DuPont Performance Polymers (DPP) announced to reveal key properties of a new high-heat resistant "Vamac" ethylene acrylic elastomer (AEM) offering heat resistance as yet unmatched in AEM at DKT 2015.

Introduced as "Vamac" VMX-5000, the new pre-compound has been designed to meet the latest challenges to automotive hoses and seals imposed by high pressure turbo charging, exhaust gas recirculation and other technologies requiring resistance to higher temperatures and aggressive fluids.

DuPont will also introduce "Vamac" VMX-2122 AEM, a new dipolymer offering better physical properties and processing performance than current AEM DP dipolymers. These improvements are coupled with enhanced colour stability, an important benefit for wire and cable applications.

The advantages of the new "Vamac" AEM compounds will be discussed in a paper to be presented at the DKT conference by DuPont Scientist Klaus Kammerer titled "New Vamac (AEM) Ethylene Acrylic Polymer Developments to Respond to Trends in the Automotive Industry" on June 29th at 15:30.
