Konson Chemical Rubber accelerator TBBS

A delayed action accelerator of vulcanization for natural and synthetic rubber. The speed of vulcanization is similar to CBS’s, but it’s delaying is larger than the CBS. There is little pollution and the color is changeless. It can be used as rubber products of tire.
