摘要： An elastomeric sanding block conformable to curved or flat surfaces includes a Shore A hardness ranging from about 30 to about 90, and is made from ethylene-vinyl acetate copolymer, low-density polyethylene or an admixture thereof. The polymer or admixture ranges from about 35 to about 70 percent of the sanding block composition by weight. A blowing agent is present in an amount that ranges from about 1.5 to about 4.5 percent of the composition by weight. The elastomeric sanding block may be formed by combining the polymer or admixture and other components under heat to yield a feedstock, thermoforming the feedstock in a mold to yield a foamed material sheet, and cutting the foamed material sheet.
