An assortment of polyurethane foam products for cushioning and insulation. Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as seating in vehicles.
Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...

Any wood used in marine upholstery must be of marine quality to resist rot and decay. [27] Typically, high-resiliency, high-density plastic foam with a thin plastic film is used to keep out water that might get by the seams. Closed-cell foam is often used for smaller cushions, which can sometimes double as flotation devices. [28]
Foam rubber was first made in 1929, by E. A. Murphy [2] and Eric Owen, two research chemists at Dunlop Rubber, who used whipped latex. In 1937, isocyanate-based materials were first used to make foam rubber. After World War II, styrene-butadiene rubber replaced many natural types of foam. Foam rubber has been used commercially for a wide range ...
High density foam Similar to memory foam mattresses, a high density foam mattress uses a more compact foam typically made from polyurethane. This kind of foam is made largely from open cells that are packed together tightly. [24] High density foam mattresses offer comfort and longevity because they are more dense than a traditional foam mattress.
