    Abstract: Artificial flowers made of polyether polyurethane and the method of their production. The ingredients of the polyether polyurethane foam product are: Group A: 10%˜99.5% polyether, 0.5%˜30% cross-linking agent, 0%˜15% stabilizer, 0.1%˜20% foaming agent, 0%˜10% color paste; Group B: isocyanate in an amount equal to 15%˜90% of the total weight of Group A ingredients. By mixing group A and group B ingredients and pouring the mixture into the cavity of a flower mold, an artificial flower of polyether polyurethane foam is produced, which has a natural look and feel resemble the real flower, resists to damages caused by squeezes and collisions, and is stable at the high temperatures of the summer time.

  • Patent number: 7230036
    Abstract: A polyurethane and/or polyisocyanurate foam is made using expandable microspheres which encapsulate a primary blowing agent. By expanding during the foam making process, the microspheres function as a blowing agent. The foam preferably has at least 10% by weight expandable micro spheres which encapsulate a non-halogenated hydrocarbon chemical or a non-halogenated hydrocarbon chemical blend and less than 2% by weight of any non-encapsulated blowing agents.
