  • POLYURETHANE FOAMS FOR COMFORT APPLICATIONS
    Publication number: 20230055474
    Abstract: Polyurethane foams that are hydrophilic but nonetheless have low compression sets are made from a combination of MDI and TDI prepolymers, water, and a polymer polyol. The foams optionally are made incorporating a phase change material in the foam formulation. The phase change material does not require encapsulation.

  • Polyurethane foams for comfort applications
    Patent number: 11485816
    Abstract: Flexible polyurethane foams are made by reacting a hydrophilic quasi-prepolymer, water and a polymer polyol in the presence of a silicone surfactant and an ethylene oxide/higher alkylene oxide block copolymer. The foams exhibit desirably low densities and compression sets, and have good thermal and moisture-wicking properties. The foams are useful in bedding and other comfort applications in which they are exposed to body heat and bear at least a portion of the weight of the user. The thermal and moisture wicking properties contribute to perceived comfort for the user.
