Abstract
Rubber compositions having excellent vibration isolating properties at a high hardness are produced by compounding 100 parts by weight of at least one of natural rubbers, diene rubbers and diene copolymeric rubbers or a rubber blend of these rubbers and a halogenated butyl rubber, 0.5-35 parts by weight of an oil modified phenol resin, a modified ratio of which is 20% or more, and 2-30 parts by weight based on said resin, of a hardening agent for the phenol resin and hardening the resulting mixture. The use of such rubber compositions is possible to make a rubber mounting to be a small size.
