THERMOSET DAMPENER MATERIAL

Thermoset compositions useful for dampening vibrations at elevated temperatures are disclosed. The thermoset compositions may have a glass transition temperature of 150° C. or greater, a tan delta peak of 0.2 or greater, and a tan delta peak width measured at half-height larger than about 40° C., as...

Summary:Thermoset compositions useful for dampening vibrations at elevated temperatures are disclosed. The thermoset compositions may have a glass transition temperature of 150° C. or greater, a tan delta peak of 0.2 or greater, and a tan delta peak width measured at half-height larger than about 40° C., as measured by dynamic thermo-mechanical analysis (DMTA) at a frequency of 1 Hz. The thermoset compositions may be used to dampen vibrations at temperatures in excess of 100° C.
