First®

ZMBT(MZ)-75

ZMBT(MZ)-80

2- mercaptobenzothiazole zinc salt

High-speed vulcanization accelerator for natural rubber and synthetic rubber. Without dyeability of rubber, MZ has the same properties as M, and the critical temperature of vulcanization is 138℃, with excellent resistance to scorch, safe operation, difficult early vulcanization and wide vulcanization flatness.

First®OTOS-80

N- oxydiethylene thiocarbamoyl -N'- oxydiethylene sulfenamide

Delayed main accelerators for general rubber such as NR, SBR, NBR and EPDM; the delay effect and processing safety are better than those of other benzothiazole and sulfenamide accelerators such as accelerators M and DM. Suitable for high temperature vulcanization, the critical temperature of vulcanization is 149℃, and the activity is great beyond this temperature; when natural rubber is vulcanized at high temperature, it has good reduction resistance, high heat resistance and small compression deformation.
