Abstract: The present invention is a method of making a polyurethane composite. The method includes forming a non-polar material into a predetermined shape and preparing its bonding through plasma treatment. Once the bonding surface has been prepared, the non-polar material is positioned in a mold and liquid precursors of polyurethane are poured into a cavity of the mold such that the liquid precursor of polyurethane is in contact with the bonding surface of the non-polar material. The liquid precursor of polyurethane is then cured to form a polyurethane material that is effectively joined to the bonding surface of the non-polar material to form the polyurethane composite material.

Abstract: A novel composite belt for an desinewing apparatus that uses a belt in combination with a perforated drum. The three layer composite has a monofilament woven polyester carcass between layers of USDA food approved urethane strengthened by adding 10% by weight of ultra high molecular weight polyethylene. The life expectancy of the invention is expected to double that of currently available belts used in such machinery.
