  • Patent number: 11970571
    Abstract: Noise, vibration, or harshness (NVH) properties of an industrial or consumer product are reduced by incorporating therein an effective amount of a polyether- or polyester-epoxide polymer (PEEP) composition. The PEEP compositions are one-component or two-component reaction products of a polyepoxide compound and a polyol composition. The PEEP compositions have a glass-transition temperature within the range of ?50° C. to 50° C. and a loss factor of at least 0.5 by ASTM D5992 over a temperature range of at least 15 Celsius degrees at one or more frequencies within the range of 0.1 to 10,000 Hz. The PEEP compositions provide NVH damping over a broad temperature range, have improved flexibility compared with conventional epoxy technologies, avoid amine and isocyanate reactants, and can be tailored to meet target specifications.
