| 摘要 |
The invention relates to a highly tear propagation-resistant rubber compound, particularly for sealing and expansion bellows, containing an elastomer, fillers and other auxiliaries. In order to achieve high tear-propagation resistance with high imperviousness, dynamic stress resistance and chemical resistance, a rubber compound is proposed which contains polychloroprene as the elastomer and amorphous silica as the filler, and which is obtained by silanising in the presence of the acid acceptor and the silica, prior to adding other additives.
