Abstract
A rubber material which is a cured rubber having a hardness of from 30.degree. as measured with an A-type rubber hardness tester to 15.degree. as measured with an F-type rubber hardness tester and an impact resilience of not less than 50%. The material has excellent vibration-proof, sound-proof, shock-absorbing or cushioning properties and is useful as a material for vibration-proof, sound-proof, shock-absorbing and cushioning members.
