Pre-dispersed accelerator TBBS(NS)-80

The pre-dispersed accelerator TBBS(NS)-80 makes the scorch time of the compound very long, the processing safety is high and the vulcanization speed is fast; it can be used alone in low-sulfur vulcanization, or it can be used with dithiocarbamate or thiuram accelerators, and the resulting vulcanizates have good heat aging resistance and high modulus; after pre-dispersing the accelerator TBBS(NS)-80 and using dithiocarbamate accelerators and thiuram accelerators, the vulcanization rate of the compound will be significantly reduced. Thiourea accelerators have a significant secondary promotion effect on the pre-dispersed accelerator TBBS(NS)-80, especially in low-sulfur compounds, while in compounds containing thiol accelerators and thiuram accelerators, the pre-dispersed accelerator TBBS(NS)-80 can delay scorch.

Pre-dispersed accelerator CBS(CZ)-80

The pre-dispersed accelerator CBS(CZ)-80 makes the scorch time of the compound very long, the processing safety is high and the vulcanization speed is fast; it can be used alone in low-sulfur vulcanization, or it can be used in combination with dithiocarbamate or thiuram accelerators, and the resulting vulcanizate has good aging resistance and compression deformation resistance; the pre-dispersed accelerator CBS(CZ)-80 and dithiocarbamate accelerator and thiuram accelerator will obviously shorten the scorch time of the compound. Thiourea accelerator has obvious secondary promotion effect on pre-dispersed CBS(CZ)-80, especially in low sulfur yellow compound. However, in the compound containing sulfur alcohol accelerator and thiuram accelerator, the pre-dispersion accelerator CBS(CZ)-80 can delay scorch and improve processing safety.

Pre-dispersed accelerator TMTD(TT)-80

The pre-dispersed accelerator TMTD(TT)-80 has very fast vulcanization speed and good scorch safety when used in natural rubber and synthetic rubber. If thiol or sulfinamide accelerators are added, vulcanization will be delayed, but the crosslinking degree will be hardly affected, only the scorch rate will be reduced and the total vulcanization time will be prolonged. Basic accelerators such as aldehyde amines and guanidines have activation effect on the pre-dispersed accelerator TMTD(TT)-80; when combined with sulfur, TMTD(TT)-80 is used as the main accelerator; When combined with thiazoles, it is used as the second accelerator; As a vulcanizing agent in sulfur-free vulcanization; Sulfur-free vulcanization or low-sulfur vulcanization can give vulcanized rubber good heat aging resistance.

Pre-dispersed accelerator TMTM(TS)-80

Pre-dispersed accelerator TMTM(TS)-80 has very fast vulcanization speed and good scorch safety when used in natural rubber and synthetic rubber. It can be used in combination with basic accelerators such as aldehyde amines and guanidine to increase its activity. As a secondary accelerator, it is used in combination with sulfenamide and thiol accelerators in technical applications. Low sulfur vulcanization gives vulcanized rubber good heat aging resistance.
