  • Patent number: 8604091
    Abstract: One- and two-part spray non-isocyanate foams that include an amide-based oligomer containing pendant carboxylic acid and a polyfunctional aziridine crosslinking agent is provided. The amide oligomer typically contains urea links, urethane links or both groups. Additionally, the foams may include one or more plasticizer, a non-functionalized resin, a surfactant, and/or a thickening agent or rheology modifier. The amide oligomer does not contain any isocyanate groups, and, as a result, there are no free isocyanate moieties generated during formation of the foam that may be potentially hazardous to workers installing the foam. The presence of the urethane segments on the oligomer permits for the generation of a polyurethane foam without the drawbacks of conventional polyurethane foams. The foams may be used to fill cavities, cracks, gaps and crevices, such as around windows and doors, and may also be used in flash and batt systems.

    Abstract: Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized triblock copolymer resin and/or a diblock copolymer resin at least partially cured into gel particles into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form a cured gelatinous elastomer or gel, which is then reduced in size, for instance to give an average particle size of 10 millimeters or less. Polymerizing the polyol and the isocyanate forms polyurethane 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 and in some cases integrating the triblock copolymer within the polyurethane polymer matrix. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink.

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.

  • Patent number: 6534555
    Abstract: Provided are catalyst systems which produce flexible polyurethane polyester foams that are color stable, are lower in odor, and uses less catalysts than current most commonly practiced technology. The use of lower amounts of catalysts with low vapor pressure reduces worker exposure to alkaline corrosive materials, reduces pollution through less pounds of volatile organic chemicals (VOC's) and is less expensive.

  • Patent number: 6420443
    Abstract: A process for preparing hydrocarbon blown rigid polyurethane foam using a novel compatibilizing agent. The compatibilizing agent is an alkoxylate adduct of a triglyceride with a hydroxyl value of about 100 or less. The triglyceride adduct has an ethylene oxide content of at least 40% by weight thereof. These adducts may be used alone or in mixture with other compatibilizers. The compatibilizers increase the stability of rigid foam formulation emulsions containing greatly increased hydrocarbon blowing agent levels while showing little or no adverse affect to physical properties of foams prepared therewith.
