Pre-dispersed accelerator ZMBT(MZ)-80
The pre-dispersed accelerator ZMBT(MZ)-80 is a quasi-overspeed and multifunctional accelerator for natural rubber and synthetic rubber, which endows vulcanized rubber with good physical and mechanical properties. Its vulcanization behavior is the same as that of the pre-dispersed accelerator MBT(M-80), the critical vulcanization temperature is 138 ℃, the vulcanized rubber has good aging resistance, it will neither change color nor pollute color, and can be used in light-colored rubber products.

Pre-dispersed accelerator MBT(M)-80
Pre-dispersed accelerator MBT(M)-80 is a kind of quasi-speed and multi-functional accelerator with long vulcanization flat period, which endows vulcanizates with good physical and mechanical properties. In sulfur-free vulcanization compound, pre-dispersed accelerator MBT(M)-80 is used as anti-scorching agent; In CR compound, it is used as vulcanization retarder; alkaline accelerators such as aldehyde amines, guanidines, etc., as well as thiuram and dithiocarbamate accelerators are used to activate MBT(M)-80.

Pre-dispersed accelerator ZEPC(PX)-80
The pre-dispersed accelerator ZEPC(PX)-80 has a fast vulcanization rate in NR, SBR, NBR, EPDM and other synthetic rubbers. The addition of thiuram and thiazole accelerators can delay the initial vulcanization and improve the processing safety. Compared with the pre-dispersed accelerators ZDBC(BZ)-80 and ZDEC(ZDC EZ)-80, the scorch time is longer and the total vulcanization time is shorter; the basic accelerator has an activation effect on it; a small amount of pre-dispersed accelerator ZEPC(PX)-80 can be used as a secondary accelerator for thiols or thiuram accelerators; it can give vulcanized rubber higher tensile strength and resilience.

Pre-dispersed accelerator ZDEC(ZDC, EZ)-80
The pre-dispersed accelerator ZDEC(ZDC EZ)-80 has a fast vulcanization speed in NR, SBR, NBR, EPDM and other synthetic rubbers. The addition of thiuram and thiazole accelerators can delay the initial vulcanization and improve the processing safety. However, compared with the pre-dispersed accelerator ZDBC(BZ)-80, its scorching time is longer and the total vulcanization time is shorter, A small amount of pre-dispersed accelerator ZDEC(ZDC EZ)-80 can be used as an auxiliary accelerator for thiol or thiuram accelerators; it can also improve the tensile strength and resilience of vulcanizates.
