DuPont to show new AEM for turbo hose and air ducts at DKT

ERJ staff report (LMH)

Geneva, Switzerland -- DuPont Performance Polymers (DPP) will showcase its new grade of ethylene acrylic elastomer (AEM), Vamac Ulta HT, at the upcoming DKT event in Nuremburg, Germany.

Vamac Ultra HT offers enhanced continuous heat resistance up to 180°C, with peaks to 200°C - significantly beyond the performance of standard AEM - making it suitable for demanding automotive applications such as turbo hoses and air ducts, DPP said in a news release.

Vamac Ultra HT also has enhanced mechanical properties such as higher flex fatigue resistance, better low temperature flexibility and superior acid resistance in exhaust gas recirculation environments, DPP noted.

DuPont will also show Viton, its the most commonly specified fluoroelastomer, which offers fuel system sealing at temperatures from -40°C to +230°C, with improved resistance to petrol, diesel, new biofuels and acid condensates from blow-by or exhaust gas recirculation, the company says. Examples of many Viton applications in fuel seals, gaskets and hoses will be on display.
