What is Polyurethane Foam?
Flexible polyurethane foam (FPF) is a polymer produced from the reaction of polyols and isocyanates, a chemical process pioneered in 1937. FPF is characterized by a cellular structure that allows a degree of compression and flexibility, providing a cushioning effect. Due to this feature, it is a preferred material in furniture, beds, automotive seats, sports equipment, medical uses, packaging, shoes and carpet cushions. It also plays a valuable role in sound insulation and filtering.
Many Performance Properties of Flexible Foam
Flexible polyurethane foam is preferred in many applications because it can be formulated with a wide range of performance properties. These range from the comfort and support required for upholstered seating, to the shock absorption used to protect packaged goods, to the long-term recovery and abrasion resistance demanded by carpet cushioning. The properties of the foam can be measured and specified very precisely to allocate the correct grade of foam to the correct application.
