  • Patent number: 10954381
    Abstract: The present invention is to provide a composition which can easily form a polyurethane resin which exerts particularly excellent damping properties in an operating temperature range. A resin composition for damping materials, including a polyol-containing component (A) and a polyisocyanate (B) is provided. The polyol-containing component (A) contains a castor oil. When the composition is cured, the peak on its Tan ? curve is 0.7 or more and the temperature for the peak is in a range of ?10° C. to 100° C.

  • Publication number: 20190300643
    Abstract: Provided is a material having an excellent sound-absorbing performance which can be easily applied to the desired area at the operation site and which can effectively prevent sound leakage The material includes a 2-part reactive urethane resin composition prepared from a polyisocyanate component and a polyol-containing component, wherein the polyol-containing component comprises a polyol component (a), catalysts (b), a foam stabilizer (c), an amine compound having primary or secondary amino groups (d), and carbon dioxide (e). The 2-part reactive urethane resin composition, when cured, is an open-cell soft polyurethane foam, wherein the average sound absorption coefficient of said polyurethane foam is 30% or more, measured in accordance with JIS A 1405-2:2007 for 63 hertz to 5000 hertz.

  • Publication number: 20080281013
    Abstract: Reduced aldehyde emissions during heated storage of a polyurethane resin are obtained by including at least one sulfurous compound selected from the group consisting of hydrogen sulfites and disulfites in the polyol component from which that polyurethane is produced. The amount of the sulfurous compound added is generally from 0.02 to 2.0 parts by weight for every 100 parts by weight of the polyol component.
