DuPont extends AEM performance with Vamac® Ultra HT for 180°C turbo hose and air duct applications
At DKT 2012, DuPont Performance Polymers (DPP) will showcase its portfolio of high performance elastomers that help automotive design engineers increase powertrain and chassis efficiency through light-weighting, turbo charging and engine downsizing — leading to increased fuel economy and reduced emissions.
A highlight will be DuPont™ Vamac® Ultra HT, a new grade of ethylene acrylic elastomer (AEM) that extends the Vamac® Ultra family of high performance elastomers. 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.
In addition, Vamac® Ultra HT delivers enhanced mechanical properties such as higher flex fatigue resistance, better low temperature flexibility and superior acid resistance in exhaust gas recirculation environments. Its higher viscosity also improves processing versus standard AEM grades, including better green strength and scorch resistance for extrusion processes.
DuPont™ Viton®, the most commonly specified fluoroelastomer, will strengthen the company’s line-up of advanced rubber products at DKT by offering fuel system sealing at temperatures from -40°C to +230°C, with improved resistance to gasoline, diesel, new biofuels and acid condensates from blow-by or exhaust gas recirculation. Examples of many Viton® applications in fuel seals, gaskets and hoses will be on display.
