    • 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.
    • 通过将100重量份的天然橡胶,二烯橡胶和二烯共聚物橡胶中的至少一种或这些橡胶和卤化丁基橡胶的橡胶共混物混合,制备具有高硬度的优异隔振性能的橡胶组合物,0.5-35份 的改性比为20%以上的油改性酚醛树脂和基于所述树脂的2-30重量份的酚醛树脂硬化剂,并使得到的混合物硬化。 使用这种橡胶组合物可以使橡胶安装成小尺寸。
