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.

High Density Polyurethane Pattern Making Foam Block Easy Composites.
If this material is used as a core for the deck of a boat will it absorb water if the outer laminate is damaged? This PU foam is a closed cell foam and so if the foam was exposed there would not really be any water uptake in the short to medium term. For example if you submerged a block of this foam in water for a number of hours and then removed it there would be almost no measureable water uptake.

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.

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. 43 44 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.

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.
