1.In the sulfur vulcanization accelerator system, the widespread
use of zinc oxide and stearic acid as activator
2.When the manufacture of transparent products, because the basic zinc carbonate soluble in rubber, which instead of active zinc oxide, available transparency
3.Non-carbon black reinforcement in the compound can be added polyols, amino alcohols active agent to reduce the silica, clay and other non-carbon black reinforcing agent on the adsorption of accelerator, so as to give full play to the accelerator efficacy.
According to the basic characteristics of various types of active agents in the use of different curing systems can be directly added dry rubber or latex, the general amount is 0.5% -3%
