Abstract
A method for making a polymeric blast media, and a product of this method. The first step involves blending a melamine compound with a cellulosic material and compression molding said first blend to produce a compression molded first blend. This first blend is then cooled and then ground. In the next step of this method, a urea compound is blended with a nano-clay material to produce a second blend and compression molded. This compression molded second blend is then ground to produce a particulate second blend. The particulate first blend is then blended with the particulate second blend. A blast media product of this method is also disclosed.

A method of making a sanding pad for removing an organic coating from a substrate comprising the steps of:
- (a) blending a liquid polymeric material with a nano-clay material to produce a first blend;
- (b) blending a cellulosic material with said first blend to produce a second blend;
- and
- (c) extruding the second blend to form a continuous sheet of abrasive material.
A product of the method of making a sanding pad for removing an organic coating from a substrate comprising the steps of:
