  • Composition for polyurethane foaming, polyurethane foam and use thereof
    Patent number: 10450403
    Abstract: A composition for polyurethane foaming, a polyurethane foam and a use thereof. The composition contains two different polyols with a polyethylene oxide ether structure and a polypropylene oxide ether structure, and a specific type of catalyst, flame retardant and water are added thereto; at the same time, the composition contains a small amount of a surfactant and other small molecular alcohols. The traits of the product are that it is pale yellow and transparent, and the product is not layered during long-term storage. The above-mentioned composition and polyphenylpolymethylene polyisocyanate (PAPI) produce a low-density polyurethane foam by means of a foaming machine.
