Abstract
A chloroprene rubber composition which contains carbon black and of which the breaking elongation A and the static modulus in shear B of the vulcanizate satisfy the following formula: A.gtoreq.-36.4.times.B+1090 (1) where A is the breaking elongation (%) and B is the static modulus in shear (kgf/cm.sup.2).
Claims5
A method for prolonging the natural period of vibration or reducing the response of a structure to vibration comprising disposition of a laminated rubber bearing between the base of said structure and its upper structure, wherein said bearing comprises a vulcanizate of a chloroprene rubber composition containing carbon black, and wherein the breaking elongation A and the static modulus in shear B of said vulcanizate satisfies the following formula:
- A.gtoreq.-36.4.times.B+1090
- where A is the breaking elongation (%) and B is the static modulus in shear (kgf/cm.sup.2).
