  • Energy absorbing flexible foams produced in part with a double metal cyanide catalyzed polyol
    Patent number: 7094811
    Abstract: Energy absorbing flexible foams can be produced by reacting an isocyanate with a first polyol, prepared at least in part by an active double metal cyanide catalyst and a second polyether polyol is prepared at least in part by a basic or acidic catalyst.
    Type: Grant
    Filed: October 3, 2002
    Date of Patent: August 22, 2006
    Assignee: Bayer Corporation
    Inventors: Neil H. Nodelman, David A. Radovich, Albert Magnotta, Carl E. Holsinger

  • Syntactic rigid PUR/PIR foam boardstock
    Patent number: 6166109
    Abstract: The present invention relates to the use of hollow microspheres filled with a hydrocarbon, to introduce uniform cell geometries in syntactic foams having a bimodal cell structure. The rigid foam product includes from 20 to 80 percent by weight of the hollow microspheres, the microspheres having average diameters ranging from 80 to 200 microns. The microspheres are encapsulated from 80 to 20 percent by weight of a closed cell polyurethane foam, the cells of the foam having average diameters from 0.01 to 60 microns.

  • Expansion of polymeric microspheres insitu in a rigid PUR/PIR foam formulation using a twin screw extruder
    Patent number: 6022912
    Abstract: The present invention relates to a process for producing a dispersion of polymeric microspheres in a polyol comprising expanding 1 to 70% by weight of polymeric beads in a polyol with a twin screw extruder to simultaneously mix and expand the beads to create a uniform dispersion of the microspheres in the polyol such that the wetting of the microspheres by the polyol is maximized.
