  • Flow-through dryer and method for rapid drying of porous foams
    Patent number: 4358899
    Abstract: A drying chamber for water laden foams supports the foam structure on a porous support and warm air is forced through the foam to dry it. An air impervious mask on the porous support around the object insures that all the air only flows through the object. Multiple objects can also be dried and loaded outside the drying chamber.

  • Flame-retardant polyurethane foams
    Patent number: 4230822
    Abstract: Improved hydrophilic crosslinked polyurethane foams are prepared by reacting (a) an isocyanate-capped polyoxyethylene prepolymer with (b) at least 20 moles of water per mole of NCO groups in the presence of (c) alumina hydrate, (d) a phosphorus fire-retardant additive and (e) an organic carbon compound which serves to react with phosphate anions at high temperatures (e.g., in the presence of a flame) and reinforces the char provided by combustion of the foam.
