DuPont Performance Polymers, is set to launch two new DuPont Vamac ethyleneacrylic elastomer (AEM) products at the International Elastomer Conference, to be held from October 12 to 15, 2015 in Cleveland, Ohio, emphasizing its commitment to developing new materials-based solutions that help the auto industry cost-effectively lower emissions and improve fuel economy to meet global regulations.
DuPont Vamac VMX5000 AEM pre-compounds can be used in seals and gaskets, air management systems and high temperature coolant hose covers that need to perform at temperatures up to 190°C. Compared with Vamac Ultra compounds, launched about 5 years ago, Vamac VMX5000 compounds increase the upper temperature limit +15 to +20°C. In certain markets they can replace fluoroelastomer (FKM) compounds where end-use temperature requirements range between 160°C to 190°C.
VMX2122 AEM is a new dipolymer that processes significantly better than Vamac DP. Studies show Vamac VMX2122 compounds can have an injection moulding cycle time under two minutes and still have good compression set values – without using a post-cure process. For extrusion applications, Vamac VMX2122 compounds do not have the die build up problems seen with Vamac DP compounds, according to a press release.
Patrick Cazuc, global marketing manager for Automotive at DuPont Performance Polymers said, “While very different solutions, together these new Vamac AEM products show DuPont’s commitment to advancing material science and building up its portfolio to support the automotive industry. Vamac AEM Elastomers are an important and growing part of our materials portfolio.”
Ed McBride, DuPont Performance Polymers technology associate will provide insight into the science behind new Vamac VMX2122 in a Specialty Elastomer session called “Improved AEM Dipolymer – Peroxide Curable” on October 15, 2015. (GK)
