Effect of Reinforcing Grade Silicon Dioxide on the Properties of a Silicone Elastomer and Its Cellular Silicone

摘要

The addition of reinforcing silicon dioxide to silicone gum has a significant effect on the properties of the elastomer and the cellular silicone cushion made from the elastomer. As the amount of silicon dioxide increases, the hardness, density, and tensile strength of the elastomer increase. Ultimate elongation is less sensitive to the filler content. In the cushion, the stiffness and compression set increase as the filler content increases, but the resiliency of the cushion decreases. (ERA citation 06:020517)
