  • Reactivity drift and catalyst degradation in polyurethane foam
    Patent number: 10385177
    Abstract: The invention is directed to methods of preparing compositions used to manufacture polyurethane foams. The invention provides methods for making compositions used to make polyurethane foams that include amine catalysts, but formulated such that catalytic potency is not diminished over time before the forming of a foam.
    Type: Grant

  • Rigid foam compositions and methods employing alkyl alkanoates as a blowing agent
    Patent number: 7635723
    Abstract: A method for producing a rigid, closed-cell polyurethane foam having a free-rise density of from about 1.3 lbs/ft.3 to about 4 lbs/ft.3 and exhibiting a shrinkage of less than 10%, comprises mixing together an isocyanate, at least one alkyl alkanoate blowing agent and at least one polyol having a hydroxyl number of from about 150 to about 800 and being selected from the group consisting of polyalkoxylated amines, polyalkoxylated ethers, and polyester polyols, to form a reaction mixture that is curable to produce such foam.
