Material Notes:
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 extrudatesEnhanced preform dimensional stabilityImproved moldability through elimination of trapped airCompounds 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.Vamac® HVG is a Vamac® G type polymer with a Mooney Viscosity of 26 compared to 16 for Vamac® G. The two polymers have similar compositions but the Vamac® HVG has a higher molecular weight. They have many common features, including:Good heat resistance in airGood oil and fluid resistanceGood low temperature propertiesCompounded with similar ingredientsCured with same cure packageThe big advantage of Vamac® HVG over Vamac® G is that the compounds made from the Vamac® HVG have a higher viscosity. The viscosity of the Vamac® HVG compound can be double that of a Vamac® G compound. This can lead to better processing. Specifically, the potential for a collapsed hose is reduced for an extrusion process and the potential for trapped air in an injection molded compound is reduced.Form: Bale size is nominally:560 mm x 370 mm by 165 mmInformation provided by DuPont.
