ABSTRACT:
The present invention has for its object to provide a damping material which, despite a high damping capacity at and around room temperature, has a small temperature dependence of rigidity at and around room temperature and a damping material having hot-melt processability and a good balance between damping capacity and temperature dependence of rigidity at and around room temperature.This invention provides a damper material compositionwherein the ratio of the storage modulus (G′) value at 0° C. to the corresponding value at 40° C. as found by the measurement of dynamic viscoelasticity in the shear mode, namely (G′0° C./G′40° C.), is not greater than 15and the loss tangent (tan δ) value as found by said measurement is not smaller than 0.4 at 0° C. to 40° C.
