Golf club grip and golf club |
摘要 |
An object of the present invention is to provide a golf club grip comprising a layer containing a polar rubber and a layer containing a nonpolar rubber, and excellent in tensile strength. The present invention provides a golf club grip comprising a polar rubber layer and a nonpolar rubber layer, wherein the polar rubber layer is formed from a rubber composition containing a base rubber including a polar rubber in an amount of 50 mass % or more, the nonpolar rubber layer is formed from a rubber composition containing a base rubber including a nonpolar rubber in an amount of 50 mass % or more, the polar rubber layer and the nonpolar rubber layer are laminated via an interlayer formed from an interlayer composition containing an olefin rubber. |

1. A golf club grip comprising a polar rubber layer and a nonpolar rubber layer,
wherein the polar rubber layer is formed from a rubber composition containing a base rubber including a polar rubber in an amount of 50 mass % or more, the nonpolar rubber layer is formed from a rubber composition containing a base rubber including a nonpolar rubber in an amount of 50 mass % or more, the polar rubber layer and the nonpolar rubber layer are laminated via an interlayer formed from an interlayer composition containing an olefin rubber, wherein the polar rubber has a solubility parameter value (SP value) (Pa1/2 (25° C.)) of 8.7 or more and 10.5 or less, and wherein the solubility parameter value is calculated according to a following mathematical formula (1):
SP value=(ΔE/V)1/2=(ΣΔei/ΣΔvi)1/2 (1) in the formula (1), ΔE represents vaporization energy, V represents mole volume, Δei represents vaporization energy of an atom or an atomic group, and Δvi represents mole volume of an atom or an atomic group. |
