VERFAHREN ZUR HERSTELLUNG THERMOFORMBARER POLYURETHANSCHAUMERZEUGNISSE |
摘要 |
A method for manufacturing a molded polyurethane article from a polyurethane foam forming composition, wherein the composition includes a polyol, an organic isocyanate compound and water, with the polyol being a polymer dispersion formed by free radical initiated polymerization of an ethylenically unsaturated monomer mixture having between 51 and 99 weight percent of an acrylic monomer with a polyoxyalkylene polyether polyol, wherein the monomer mixture represents between about 25 to 75 weight percent of the dispersion. After the foam is formed from the foam forming composition, it is molded under heat and pressure to form a molded polyurethane article. |
