  • Heat-storage composition
    Patent number: 10968379
    Abstract: A heat-storage composition includes a resin and a heat storage material. The composition has a viscosity of 100 to 1,000 dPa·s, as measured with a cylinder-type rotational viscometer. The composition also has a storage elastic modulus (G?) of 3 Pa or more at an angular frequency of 1 rad/s, as measured by a dynamic viscoelasticity measurement method at a temperature of 25° C. and at a strain of 0.1%.
