Pre-dispersed NOBS-70 makes rubber scorch quite a long time, high processing safety and vulcanized very complete. In the sulfur vulcanization accelerators may be used alone as the primary use, but also salts with dithiocarbamate or thiuram accelerators and dried, the resultant vulcanized rubber has good heat aging properties and good compression set. Pre-dispersed NOBS-70 and salts with dithiocarbamates and thiuram accelerators promoting agents of rubber scorch time will be significantly reduced. Thiuram accelerator TMTM-70 with a pre-dispersed NOBS-70 was particularly visible with the degree of cross-linking promoting shorter cure time, and has good scorch resistance, and the effect of the high. In the low-sulfur yellow rubber compound, sulfur alcohol accelerator and thiuram accelerators rubber compound, pre-dispersed NOBS-70 could delay scorch.
