Polyurethane is formed by the reaction of a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Polyurethane can be categorized into two major types; polyester, and polyether. These are both elastomers. Both are abrasive resistant, while polyester has a sliding quality and polyether is abrasion-resistant.
