Vamac® Ultra IP Datasheet,AEM,DuPont Performance Elastomers-SHANGHAI SUSHENG

Message
The latest manufacturing technology allows polymerization of AEM grades with optimized structure and chemical composition, which provides significant improvements over the existing standard DuPont ™ Vamac® elastomers. These grades, designated and sold as Vamac® Ultra, provide true step-change improvement in processability, performance and customer value for targeted applications. Vamac® Ultra IP (developmental name VMX-3040) is the first of the Ultra family products to be commercialized. During the development phase, a goal was to identify a product having improved performance in injection molding processes compared to Vamac® G to reduce the frequency of mold cleaning. The high viscosity of Vamac® Ultra IP compared to standard AEM grades results in better mixing as well as increased green strength of compounds, and helps to avoid collapse during extrusion processes. The optimized polymer structure ensures gains in physical properties resulting in improved performance of rubber parts such as seals, dampers and extruded hoses. Low abrasion values may allow extended use of Vamac® Ultra IP in dynamic seals. The best physical properties of Vamac® Ultra IP are obtained in rubber parts having a hardness range between 50 and 90 Shore A. Extensions of this hardness range may be more easily achieved with Vamac® Ultra IP than standard AEM using appropriate compounding. Vamac® Ultra IP combines dry heat resistance of 175 °C over a period of 1000 h (six weeks) with very good resistance to automotive lubricants. Exposure of peak temperatures of 200 °C are possible for up to four days. At the same time, the Tg of -31 °C provides very good low temperature flexibility. Good compression set and compressive stress relaxation properties make Vamac® Ultra IP an excellent choice for sealing applications. Good resistance to Blow-By (hot air, acids, oil and petrol fumes), present in automotive crankcase venting systems and air ducts combined with increased dynamic resistance are additional attributes of Vamac® Ultra IP. Like every other grade of Vamac® , Vamac® Ultra IP is halogen-free.
