Abstract
Sanding blocks that are readily conformable to curved or flat surfaces are disclosed herein. In one embodiment, a hand-held sanding block is disclosed that is an elastomeric sanding block conformable to curved or flat surfaces, wherein the elastomeric sanding block has a Shore A hardness ranging from about 45 to about 90, and wherein the elastomeric sanding block is made from a polymeric composition formulated from a plurality ingredient that includes an admixture of an ethylene-vinyl acetate copolymer and a metallocene catalyzed ethylene-&agr;-olefin copolymer, and a blowing agent. Also disclosed are methods for manufacturing sanding blocks. Some of the more significant features associated with the inventive sanding blocks disclosed herein include: (1) sized to perfectly use the entire sanding surface area of a standard sheet of sandpaper due to an optimized outer perimeter length, which length allows such standard sheet of sandpaper to be more effectively wrapped thereabout; and (2) solves shortcomings associated with cumbersome practice of wrapping sandpaper about paint sticks.
