Disclosed is a polyurethane foam and a method of preparing the same which utilizes only bio-renewable polyols and no petroleum derived polyols. The polyol is derived from a bio-renewable source and has a bio-renewable content of at least 70% by weight. The produced foams have mechanical and performance properties that are equal to or exceed those of similar polyurethane foams produced using petroleum derived polyols. The foams are preferably formed into sponges and other cleaning products for use by consumers and in industrial settings.

Bio-renewable polyurethane foam for consumer cleaning applications

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.

Flexible polyurethane foam with suspended particles

A direct and simple method to control cell size in a polyurethane foam is disclosed. Polyurethane foam is made by mixing prepolymer with foam-forming ingredients comprising isocyanate and water which react to give carbon dioxide. The reaction is driven by a catalyst and results in a foam structure with cells of a particular size. Using the addition of a pre-determined amount of mineral oil, the coalescence of neighboring cells of the foam structure may be advantageously controlled to form a cell structure with a desired average cell size.
