    MDI (methylene diisocyanate) based polyurethane foams and applications. Developed fast reacting MDI-based polyurethane foam formulations for automotive headrests. process, and manufacturing development team for automotive seating and other soft trim applications. The global polyols market is segmented on the basis of type, application, end-user and geography. In terms of type, the market is segmented into Polyether Polyol and Polyester Polyol. Based on applications, the market is segmented into polyurethane rigid foam, polyurethane flexible foam, CASE (coating, adhesive, sealant and elastomer) and others. ISOFOAM ® rigid and FLEXOCEL ® flexible and integral skin foam systems produce foams varying in density, hardness and surface characteristics that satisfy the broadest spectrum of flexible, semi-flexible and rigid foam applications. Applications include RIM automotive parts, Integral skin moldings, thermal and structural insulation such as. Polyurethane foam (including foam rubber) is sometimes made using small amounts of blowing agents to give less dense foam, better cushioning/energy absorption or thermal insulation. In the early s, because of their impact on ozone depletion, the Montreal Protocol restricted the use of many chlorine-containing blowing agents, such as trichlorofluoromethane (CFC).

    For innovative and cost-effective fabricated foam packaging, American Foam Products should be your preferred vendor! We utilize a wide range of foams and other materials, including polyethylene, polyurethane, crosslink polyethylene, expanded polystyrene and plastic corrugated, as well as a broad range of manufacturing services and capabilities.
