  • Patent number: 9914813
    Abstract: A polyrotaxane is blended into a polyol composition, which can reduce the tensile stress of a flexible polyurethane foam. A vertical compressive stress due to the weight of a sitting user and a tensile stress due to the input of lateral vibrations act on a urethane pad. However, by reducing the tensile stress of the flexible polyurethane foam, the direction (inclination) of a resultant force obtained by combining the compressive stress and the tensile stress can be brought close to the vertical direction. Thus, the angle of inclination of the user's hip (ischium) on the urethane pad to the vertical direction due to the input of lateral vibrations can be reduced, so that the sense of wobble of the urethane pad can be reduced.

The green tea memory foam is used to make pillows, cushions and mattresses. Green tea foam in the top layer of a mattress acts as an antiodorant such that less of the chemical smell of the memory foam is perceived by the user. In addition, the bacteria and mold that would otherwise develop in the moist warmer sleeping environment on memory foam are killed by the green tea additive to the foam. Measurable antimicrobial and antiodorant qualities in the green tea foam are achievable by adding green tea powder constituting less than 2% of the weight of the resulting green tea foam. A neck-support contour pillow is made using memory foam that contains green tea and a green dye.

  • Patent number: 8604093
    Abstract: A fire-resistant polyurethane foam is provided. A hydroxyl-containing inorganic fire retardant is premixed with a polyisocyanate and a polyol, respectively, to form two premixtures. Then, the two premixtures are mixed for reaction to form a fire-resistant polyurethane foam. Preferably, a combination of different particle sizes of the fire retardant is employed to maximize the amount of the fire retardant and increase the fire resistance of the foam.

  • Publication number: 20130295371
    Abstract: Combinations of gelatinous elastomer containing one or more phase change materials, known as “phase change gel”, and polyurethane foam may be made by introducing at least partially cured phase change gel particles comprising plasticized triblock copolymer resin and/or diblock copolymer resin and one or more phase change materials, into a mixture of polyurethane foam-forming components including a polyol and an isocyanate. The phase change gel can be crosslinked to form a cured gelatinous gel, which is then reduced in size before introduction. After the foam-forming components polymerize to make polyurethane foam, the phase change gel particles are discrete visible particles dispersed throughout the foam. The polyurethane reaction is exothermic and can generate sufficient temperature to at least partially melt the styrene-portion of the triblock copolymer resin thereby extending the crosslinking.
