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.
Major Performance Properties and Applications
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.
