  • INSULATION MATERIAL
    Publication number: 20150274390
    Abstract: A flexible or rigid heat-insulation material consisting of a sheet of at least one layer of closed-cell gas bubbles 1/16 inch to 1 inch in size filled with a gas selected from helium, argon, neon, krypton, xenon, carbon dioxide, and chlorodifluoromethane, and mixtures thereof. At least one heat reflective layer of aluminum film is adhesively attached to the layer of gas bubbles or an aluminum film is vapor-deposited on the layer of gas bubbles.
    Type: Application
    Filed: June 15, 2015

  • Foam, composition and method of production, containing polyurethane, polyisocyanurate and polyurea groups
    Patent number: 4880848
    Abstract: Ternary polyurethane-polyisocyanurate-polyurea foams having, by weight of the reaction product, 10 to 35 percent polyurethane, 30 to 55 percent isocyanurate and 20 to 45 percent polyurea, and having a light-weight density in the range of 0.5 to 0.9 pounds per cubic foot, overcome the normal fragile nature and friability of polyisocyanurate and polyurea components while rendering the polyurethane component essentially fire resistant. The resultant foam has excellent heat insulating properties, is semi-flexible, extremely light in weight, and can be inexpensively produced by existing two-component foam dispensing equipment.
