ABSTRACT:
An industrial sponge device and a method of manufacturing the same. The sponge is made from a polyvinyl acetal material with a process in which the pores are formed by gas to provide an open pore structure having no fibrils. Additionally, the sponge is purified by alternating exposure of the partially cross-linked sponge to solutions of high pH and low pH. The sponge is sterilized by electron beam radiation to destroy micro organisms that can cause contamination of the final product. The resulting sponge material is formed into an industrial sponge having a cylindrical body and a plurality of projections extending from the body. The projections are tapered truncated cones having a cross-sectional radius that decreases with distance from the body.
