  • Medical Device Link .
    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
  • Foam-friendly fridges
    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
  • Medical Device Link . The Interaction of Plasma Proteins and Platelets with a Homologous Series of Polyurethanes
    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
