Abstract
The present disclosure describes a flexible polyurethane foam having suspended within its matrix particles of silicon dioxide, SiO. The particles of silicon dioxide are interspersed within the polyurethane matrix and protrude from the surface of the foam. These particles form an abrasive surface and the produced foam finds use as a cleaning material. The foam includes the use of a pre-polymer polyol formed by the reaction of triol polyol having a molecular weight of from 700 to 8000 with a polyisocyanate and a tin catalyst. The produced foam is much more durable than commercially available melamine foams and is an effective cleaning foam.
