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 Foams rigid polyurethane foam polyisocyanurate formulations polyurethane formulas.
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.
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.
Flexible Polyurethane Foam.
4.3 Toluene Diisocyanate TDI. 4.4 Toluene Diamine TDA in Foam. 4.6 Absence of Residues in Foam. 4.7 IMDS and GADSL. 4.9 Recycling Re-Use and Recovery of PU Foam. 5.2 Resistance to Fungal and Microbial Growth. Flexible foams have many applications in upholstery including chair seats backs arm rests loose cushions tops for stools mattresses pram cushions and padding and carpet underlay. They have brought comfort into sitting and sleeping and into leisure activities such as camping and caravanning. Cleanliness may be added to comfort properties because the foams are biologically clean when new and they have inherent bacteriostatic properties.
