MOSCOW (MRC) -- DuPont Performance Polymers is presenting two new Vamac AEM products at the International Elastomer Conference, emphasising its commitment to developing new materials-based solutions that help the automotive industry cost-effectively lower emissions and improve fuel economy to meet global regulations, as per GV.
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, the new products increase the upper temperature limit by +15 to +20 C. According to the manufacturer, in certain markets they can replace FKM compounds where end-use temperature requirements range between 160 C to 190 C.
Vamac VMX2122 AEM is a new dipolymer that is said to process significantly better than Vamac DP. Studies show Vamac VMX2122 compounds can have an injection moulding cycle time under 2 min and still have good compression set values - without using a post-cure process, says DuPont. For extrusion applications, Vamac VMX2122 compounds do not have the die build up problems seen with Vamac DP compounds.
"The combination of improved processing and elimination of the post cure step are two attractive features of the Vamac VMX2122 compounds," said Ed McBride, DuPont Performance Polymers technology associate, who will provide insight into the science behind new VamacVMX2122 in a Specialty Elastomer session called "Improved AEM Dipolymer - Peroxide Curable" on Thursday, 15 October 2015 at 9 a.m.
As MRC reported earlier, DuPont completed the separation of its Performance Chemicals segment through the spin-off of The Chemours Company on 1 July 2015.
DuPont is an American chemical company that was founded in July, 1802. The company manufactures a wide range of chemical products, leading extensive innovative research in this field. The company is the inventor of many unique plastics and other materials, including neoprene, nylon, Teflon, Kevlar, Mylar, Tyvek, etc. DuPont was the developer and main producer of Freon used in the production of refrigeration equipment.
