Celanese/Dupont Vamac® AEM Vamac ULTRA LS Ethylene acrylic elastomers

Vamac® Ultra LS is a high viscosity version of Vamac® GLS, offering improved performance in injection  molding processes compared to Vamac® GLS to reduce the frequency of mold cleaning.The high viscosity of Vamac® Ultra LS compared to standard AEM grades results in better mixing, provided  mixing conditions are adapted to requirements of polymers with higher viscosity. Increased green strength of  compounds 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.  The best physical properties of Vamac® Ultra LS are obtained in rubber parts having a hardness range between  50 and 90 Shore A. Extensions to the lower hardness range may be more easily achieved with Vamac® Ultra  grades than standard AEM using appropriate compounding. Among AEM, Vamac® Ultra LS offers the best compression set and fast cure with low oil swell useful such  applications as oil seals, oil cooler hose, and PCV hose.
