The application of neodymium based cis-1,4-polybutadiene rubber (Nd-BR) BR 9101 N in the formula of support compound of run-flat tire was studied, and compared with those of foreign same type product Nd-BR CB 24.The results showed that Nd-BR BR 9101 N could meet the requirements for incoming inspection of Nd-BR raw material, and the basic compoundi
Greases have a variety of advantages when special operating conditions apply for gear lubrication, e.g.improved properties against continuous (or slow speed) wear.Often, gears with different surface hardness are combined, in order to reduce costs during manufacturing and heat treatment.However, this has detrimental effect on the wear lifetime.Conse
