molding. Polyurethanes ' unique chemistry gives them this versatility. They are segmented polymers, meaning they have a soft segment that provides flexibility and a hard segment that provides strength. Polyurethanes are made from three basic building blocks: the backbone, the diisocyanate, and the chain
Ever more stringent standards for energy efficiency force designers to plan carefully for the foam-insulation process. When a cabinet is filling with polyurethane foam, many physical and chemical reactions happen at once. Polymer formation reactions take place. The reaction of diisocyanate

JAMES M. LAMBERT AND KEVIN G. TINGEY olyurethanes of similar bulk composition-- all using the same diisocyanate, chain extender, and soft-segment type--were synthesized in microparticle form. This homologous series of polyurethanes, which varied in morphology and surface structure, was prepared
Where foam fits in medical design
polyurethane foam -- the most common type of foam -- is the product of petro-chemistry and resins. More precisely, it's made of toluene diisocyanate, polyol and water. These ingredients are mixed, poured onto a linear conveyor, then left to "rise " and cure. Additives are blended in for specific
