Grip rubber composition and golf club grip

Abstract

An object of the present disclosure is to provide a grip rubber composition from which a crosslinked rubber having a great frictional coefficient can be obtained. The present disclosure provides a grip rubber composition containing a base rubber and a vulcanizing agent, wherein the base rubber contains a solid rubber that is a solid at a temperature of 25° C. and a liquid rubber that is a liquid at a temperature of 25° C., and a ratio (tan δ/E*) of a loss tangent (tan δ) to a complex elastic modulus (E*) (MPa) of a cured product of the grip rubber composition at a temperature of 25° C. ranges from 0.030 to 0.045, wherein the loss tangent (tan δ) and the complex elastic modulus (E*) (MPa) are measured with a dynamic viscoelastic spectrometer under measuring conditions of an oscillation frequency: 10 Hz, a strain amplitude: 0.05% and a tensile mode.
