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.
Polyurethane Applications.
These wood panels are used in structural sheathing and flooring manufactured housing joists and beams and shop panels. The production of rebond foam used under carpet primarily uses polyurethane binders and chemicals to bind the scrap foam which is often flexible polyurethane foam into the flooring underlay. Waterborne Polyurethane Dispersions PUDs. Waterborne polyurethane dispersions PUDs are coatings and adhesives that use water as the primary solvent. With increasing federal regulation on the amount of volatile organic compounds VOCs and hazardous air pollutants HAPs that can be emitted into the atmosphere PUDs are being used in more industrial and commercial applications. When scientists discovered that polyurethanes could be made into fine threads they were combined with nylon to make more lightweight stretchable garments.

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. Filling of spaces and cavities edit. Two binary liquids one of which is a polyurethane either T6 or 16 when mixed and aerated expand into a hard space-filling aerosolid. Construction sealants and firestopping edit.

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.

The physical shape of the struts and the absence or presence of windows voids also play a major role in foam physical performance. HOW DENSITY AFFECTS FOAM PERFORMANCE. Foam surface firmness is independent of foam density. High density foams can be produced very soft and low density foams can be made very firm. Therefore there is no such thing as a hard or soft density. High density foam products generally offer a great deal of support but they may actually be fairly soft foams. There is a difference between firmness and support. Firmness 25% IFD is a measurement of surface feel of the foam.
