  • Polyurethane molded article and production method thereof
    Publication number: 20060141236
    Abstract: The amount of aldehyde emitted from a polyurethane and molded articles made of a polyurethane is reduced. The reduction of aldehyde emissions from polyurethanes is achieved by including a hydrazine compound as an aldehyde-scavenger in the polyol component of the polyurethane-forming reaction mixture. The hydrazine compound is used in an amount of 0.05 to 3.0 parts by weight, based on 100 parts by weight of the polyol mixture. Aldehyde emissions from molded polyurethane articles are reduced by including a hydrazine compound in the mold coating material in an amount of from 0.1 g/m2 to 10 g/m2.
