Close collaboration between DuPont and wire and cable makers to develop optimum formulations using Vamac® has resulted in a unique combination of properties that outperform other commonly used polymers for flame-retardant cables and hoses, such as ethylene vinyl acetate (EVM). Optimized Vamac® compounds combine enhanced fire and oil resistance with better low temperature flexibility (without plasticizer), and superior heat resistance up to 175°C.
Cables with jacketing of halogen-free flame-retardant (HFFR) compounds based on DuPont™ Vamac® DP ethylene acrylic elastomer (AEM) provide new levels of safety, durability and ease of installation in confined spaces for highly regulated railway, automotive, marine, and military applications.
DuPont (NYSE: DD) has been bringing world-class science and engineering to the global marketplace in the form of innovative products, materials, and services since 1802. The company believes that by collaborating with customers, governments, NGOs, and thought leaders we can help find solutions to such global challenges as providing enough healthy food for people everywhere, decreasing dependence on fossil fuels, and protecting life and the environment.

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.
