| DuPont™ Vamac® HVG is an unfilled gum ethylene/acrylic elastomer similar to Vamac® G, but offering higher compound viscosity. The higher viscosity of compounds made with Vamac® HVG results in improved green strength and related processing advantages, such as: Improved collapse resistance of extrudates; Enhanced preform dimensional stability; and Improved moldability through elimination of trapped air. Compounds of Vamac® HVG are often selected for applications such as compression molded goods, highly plasticized compounds, and extruded tubing and hose. Vamac® HVG contains a small amount of processing aid and has a nominal specific gravity of 1.04. It has a mild acrylic odor.&& |
