Polyurethane is a resilient, flexible and durable manufactured material that can take the place of paint, cotton, rubber, metal or wood in thousands of applications across virtually all fields. It can be hard like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber or sticky like glue. Since its invention during the 1940s, polyurethane has been used in a wide range of items, from baby toys to airplane wings, and it continues to be adapted for contemporary technology.
