  • PROCESSES FOR MAKING MOLDED FLEXIBLE FOAMS AND FLEXIBLE FOAMS PRODUCED THEREBY
    Publication number: 20220235168
    Abstract: A process for making a molded flexible foam. The processes includes: (a) depositing a foam-forming reaction mixture onto a surface of a mold cavity, and (b) allowing the foam-forming reaction mixture to react in the mold cavity. The foam-forming reaction mixture includes: (1) a polyisocyanate present in an amount of less than 45% by weight, based on the total weight of the reaction mixture; (2) an isocyanate-reactive composition; (3) a blowing agent; and (4) a catalyst.

  • Methods for preparing open-celled polyurethane foams, systems for use therein, and open-celled polyurethane foams produced thereby
    Patent number: 10494498
    Abstract: Disclosed are methods and systems for preparing open-celled polyurethane foams by a discontinuous box foam process in which (a) a polyurethane foam-forming composition is deposited into a container having a gas-permeable base and (b) the polyurethane-foam forming composition is allowed to form an open-celled polyurethane foam in the container. In these methods and systems, the gas-permeable base is heated before, during, and/or after step (a) and heating is continued during at least a portion of step (b).
