A polyurethane material, or PU material for short, is a type of versatile plastic. The three types of PU materials are flexible foams, rigid foams and elasto-plastics. These materials are most often used in building construction, the automotive industry and in furniture manufacturing.
Polyurethane is a popular construction material because of its ability to be molded into various shapes and strengths. PU materials are used to make many everyday products, such as furniture, toys, insulation, and paints.
The first polyurethanes were produced in Germany in 1937 by Otto Bayer and I.G. Farben. These materials were first used on aircraft during World War II.
