Polyurethane is a polymer the molecular structure of which may cross-link and become a thermosetting plastic, or stay linear and remain thermoplastic. Thermosetting polyurethane molecules cross-link into a single giant molecule. Thermosetting polyurethane is widely used in various forms, including soft and hard foams. Soft, open-celled polyurethane foams are used to make seat cushions, mattresses, and packaging. Hard polyurethane foams are used as insulation in refrigerators, freezers, and homes. Thermoplastic polyurethane molecules have linear, highly crystalline molecular structures that form an abrasion-resistant material. ..full definition

A group of polymers with a variety of uses – in products ranging from shoe soles to furniture upholstery and from insulation foams to coatings, paints and adhesives. Different types of isocyanates are used in the production of polyurethanes. Toluendiisocyanate (TDI) and 4,4â€(tm)-diphenylmethanediisocyanate (MDI) are of special concern since both may cause allergic reactions and asthma. Polyurethane is a relatively stable compound but when broken down emits aromatic amines, which can cause cancer.
