DuPont Performance Polymers has introduced Vamac VMX5000, a new family of ethylene acrylic elastomer (AEM) pre-compounds that it says extends the upper temperature limit for AEM applications by 15 to 20°C.
The company says this material is currently under evaluation by major auto OEMs and Tier 1 suppliers for seals and gaskets, air management system applications and high-temperature coolant hose covers. Benefits are said to include lower cost and lower specific weight, in a temperature range between 160°C to 190°C. – especially where standard acrylic, ethylene vinyl acetate or AEM elastomers are no longer considered.
