Speciality rigid foam manufactures sell foam that replace wood in carved sign and 3D-topography industries. PU foam is also used as a thermal insulator in many houses. Polyurethane resin is used as an aesthetic flooring material. Being seamless and water resistant it is gaining interest for use in modern interiors especially in Western Europe. Polyurethane being used as an insulator in house construction. Polyurethane used as a flooring material. Being poured as a liquid after which it hardens polyurethane is a floor material that can be applied seamlessly. Filling of spaces and cavities edit.
Rigid Polyurethane Foam.
Heating and cooling costs amount to 50 to 70 percent of the energy used in the average American home according to the U.S. To help reduce these costs maintain uniform temperature and lower noise levels in homes and commercial properties builders turn to rigid polyurethane and polyisocyanurate polyiso foamone of todays most effective insulation materials available for roof and wall insulation insulated windows and doors and air barrier sealants. Rigid polyurethane and polyiso products deliver a unique combination of properties as described below.

Unlike thermoplastic foams PVC SAN the unit cost of polyurethane foam increases in a more linear fashion with density e.g a 20-pound per cubic foot polyurethane foam will be approximately twice the cost of a 10-pound foam. There can be considerable differences in foam strength at the same density depending on the foam production process used. This results from differences in chemical formulation required to make foams via different production methods and the curing temperature of the foam while in production. Also if flammability is a concern it is useful to know what kind of blowing-agent is employed to create cells in the foam. Many producers use carbon-dioxide a by-product of the foam-making chemical reaction to create cells in their foams.
What is polyurethane foam? Europur.
As simple explanation manufacturers make polyurethane foam by reacting polyols and diisocyanates both products derived from crude oil. A series of additives are necessary to produce high-quality PU foam products depending on the application the foam will be used for. Each form of polyurethane foam has many uses. EUROPUR represents the producers of flexible polyurethane foam blocks used in the applications presented on this website bedding furniture automotive and many others. Some flexible PU foams are also moulded especially for use in the automotive sector mainly for car seats. For more information on moulded foam applications please visit the website of Euro-Moulders the European association of manufacturers of moulded polyurethane parts for the automotive industry.

This is of particular interest in the area of polyurethane coatings where light stability is a critical factor and is the main reason that aliphatic isocyanates are used in making polyurethane coatings. When PU foam which is made using aromatic isocyanates is exposed to visible light it discolors turning from off-white to yellow to reddish brown. It has been generally accepted that apart from yellowing visible light has little effect on foam properties. 41 42 This is especially the case if the yellowing happens on the outer portions of a large foam as the deterioration of properties in the outer portion has little effect on the overall bulk properties of the foam itself.

Flexible Polyurethane Foam.
Flexible polyurethane foam FPF affects our lives in many ways and new applications are rolling out on a regular basis. It is used as cushioning for a wide variety of consumer and commercial products including furniture carpet cushion transportation bedding packaging textiles and fibers. FPF usage consists mostly of slabstock which is used primarily for carpet cushion and furniture. Most of the remainder is used by the transportation industry for automotive interiors and other purposes. FPF cushions upholstered furniture office chairs stadium seating and auditorium seating.
