VMX-2122 Introduction Vamac® ethylene acrylic elastomer, introduced in 1975, has been successfully used for many years in demanding automotive applications, where excellent resistance to heat, engine and transmission fluids or Blow-By is required. DuPont’s latest manufacturing technology allows production of enhanced AEM grades that are significantly improved compared to the existing standard Vamac® elastomers. These grades, designated and sold as Vamac® Ultra, provide a true step-change improvement in processability, performance and customer value for targeted applications. The new manufacturing technology has now also been applied to a new EMA Dipolymer, called VMX-2122. Major Performance Properties and Applications Higher viscosity is the major difference between the standard AEM grades and the Vamac® Ultra family of polymers, of which four Terpolymers, cured by Diamine curatives, have been already commercialized. VMX-2122 is a high viscosity version of Vamac® DP. It provides good mold release, comparable to Vamac® Ultra Terpolymers. Increased green strength of compounds helps to avoid collapse during extrusion processes, and may help in applying reinforcement layers without cutting the inner tube by filaments. The optimized polymer structure ensures gains in physical properties, resulting in improved performance of rubber parts such as cables, seals, gaskets or extruded hoses. Best physical properties of VMX-2122 are obtained in rubber parts having a hardness range between 50 and 90 Shore A. Handling Precautions Because VMX-2122 contains small amounts of residual methyl acrylate monomer, adequate ventilation should be provided during storage and processing to prevent worker exposure to methyl acrylate vapor. Additional information may be found in DuPont Material Safety Data Sheet (MSDS), and bulletin, Safe Handling and Processing of Vamac® (VME-A10628), available from DuPont Performance Polymers. Like every other grade of Vamac®, VMX-2122 is halogen-free. Typical properties of this new experimental polymer are shown in Table 1.
