  • Method of forming high resilience slabstock polyurethane foam
    Patent number: 6797736
    Abstract: The subject invention provides a method of forming high resilience slabstock polyurethane foam having random cell structures to produce latex-like feel and characteristics. The method includes the first step of providing an isocyanate-reactive component and an isocyanate component to react with the isocyanate-reactive component. A first nucleation gas is provided under low pressure and is added into at least one of the isocyanate-reactive component and the isocyanate component to produce a first cell structure in the polyurethane foam. A second nucleation gas is provided under low pressure, being different than the first nucleation gas, and is added into at least one of the isocyanate-reactive component and the isocyanate component to produce a second cell structure in the polyurethane foam that is different than the first cell structure.
