Polyurethane is a versatile polymer composed of organic units joined by carbamate (urethane) links. It is formed by reacting a polyol with a diisocyanate or a polymeric isocyanate in the presence of catalysts. Polyurethanes can be produced in a wide range of forms, from flexible foams and rigid foams to elastomers, coatings, adhesives, and fibers. The specific properties of a polyurethane depend on the choice of diisocyanate and polyol, as well as the additives used during manufacturing.

The application of polyurethanes is extensive. Flexible foams are commonly found in furniture cushioning, bedding, and automotive seating. Rigid foams are excellent insulators and are used in construction for walls, roofs, and appliances like refrigerators. Polyurethane coatings provide durable and protective finishes for floors, wood, and metal. Polyurethane elastomers are used in applications requiring high abrasion resistance and flexibility, such as in shoe soles, wheels, and hoses. The material's ability to be tailored to specific needs makes it a valuable component in many industries, including automotive, construction, furniture, and footwear.
