| 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. |
