Vamac® Ultra HT achieves continuous heat resistance up to 180°C, with peaks to 200 °C, which, coupled with improved mechanical properties, identify it as an ideal candidate for demanding automotive applications such as turbo hoses and air ducts.
DuPont™ Vamac® Ultra HT ethylene acrylic elastomer (AEM) offers continuous heat resistance up to 180°C, with peaks to 200°C, higher flex fatigue resistance and enhanced mechanical properties, better low temperature flexibility and superior acid resistance in blow-by gas and exhaust gas recirculation environments than standard AEM, making it an ideal candidate for automotive turbo hoses and air ducts.
“Vamac® Ultra HT is designed to answer the need for high performance hoses in modern automotive engines, and especially to meet the demand for higher temperature resistant turbocharger hoses and ducts. Its dynamic performance and superior thermal resistance mark a further step in the development of the Vamac® product range, while processors will continue to benefit from an accommodating polymer for their formulations,” said Patrick Cazuc, Automotive Director Europe, DuPont Performance Polymers.The latest manufacturing technology for Vamac® enables the polymerization of AEM grades with optimized structure and chemical composition, resulting in significant improvements over existing standard Vamac® elastomers.

Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix. Until today, the question about the exact anatomical origin of these fibroblasts has not been answered. In order to find potential ways of influencing the scarring process, the team of Dr. Yuval Rinkevich, Group Leader for Regenerative Biology at the Institute of Lung Biology and Disease at Helmholtz Zentrum München, aimed to finally find an answer. As it was already known that all scars derive from a fibroblast lineage expressing the Engrailed-1 gene - a lineage not only present in skin, but also in fascia - the researchers intentionally tried to understand whether or not fascia might be the origin of fibroblasts.

Research from a leading international expert on the health of the Great Lakes suggests that the growing intensity and scale of pollution from plastics poses serious risks to human health and will continue to have profound consequences on the ecosystem.

Conventional light microscopes cannot distinguish structures when they are separated by a distance smaller than, roughly, the wavelength of light. Superresolution microscopy, developed since the 1980s, lifts this limitation, using fluorescent moieties. Scientists at the Max Planck Institute for Polymer Research have now discovered that graphene nano-molecules can be used to improve this microscopy technique. These graphene nano-molecules offer a number of substantial advantages over the materials previously used, making superresolution microscopy even more versatile.
Microscopy is an important investigation method, in physics, biology, medicine, and many other sciences. However, it has one disadvantage: its resolution is...
