Title: Composite polymer blast media

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.
