Fridge doors contain polyurethane foams.
Polyurethanes are polymers or compounds made of large molecules, including urethane. Polyurethanes are often used in the form of flexible or rigid foams. According to the Center for the Polyurethanes Industry, flexible foam is used in upholstered furniture and cars, while rigid foam is employed as insulation in freezers, fridges and in the building industry.
Transportation Industry
Polyurethane foams are used throughout cars, including arm rests, head rests, cushioned instrument panels and other parts such as bumpers and steering wheels. These foams offer a sustainable option for the industry, as they can be recycled to make carpeting for houses and cars. The use of polyurethane foams in the transportation industry has increased nine percent since 1998, according to the Center for the Polyurethanes Industry.
Insulation
Rigid polyurethane foam is used to reduce the energy required to keep refrigerators and freezers cold. According to the European Diisocyanate and Polyol Producers Association, polyurethane rigid foams have a long service life, allowing a household electricity reduction of up to 30 percent. These foams can also be used in building insulation, including cavity walls, roofs, floors and around pipes and boilers.
Upholstered Furniture
Flexible polyurethane foams are used as a filling material for cushions, mattresses and upholstered furniture, and can be produced in different densities. Memory foam is a form of polyurethane, which adapts to the shape of a person's body. It is used in hospitals because it prevents pressure sores in people who spend long periods in bed, reports the European Diisocyanate and Polyol Producers Association.
