Urethane foam is most commonly used to refer to a material made from polyurethane. Polyurethane (PU) stands for an important group of products within the big family of polymers or plastics. PU is a generic name for a wide range of foam types.
In 1937, Otto Bayer invented the process to manufacture polyurethanes. When it was first created, polyurethane was used as a rigid foam in airplane wings throughout World War II. After the war, people began experimenting with different uses.
Urethane foam is an artificial material with several different uses. The manufacturing process can produce foams of varying densities and flexibilities, which means that it can serve functions as diverse as mattresses, upholstery cushioning, packaging foam and rebond carpet pads.
