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.
