Rubber Accelerator ZMBT (MZ)
Identification:
Chemical Name: Zinc 2-mercaptobenzothiazole
Synonym: Zinc di(benzothiazol-2-yl) disulphide; Rubber Accelerator MZ; pennaczt;
Structural Formula:
Molecular Formula: C14H8N2S4Zn
Properties: It is light yellow powder (granule) with a little bitter, no poison. The density is 1.70(20℃), the decomposable temperature is 300℃. It is soluble in chloroform, acetone, partly soluble in benzene, ethanol, CCl4, insoluble in gasoline, water and ethyl acetate. It is decomposing when meeting strong acid and strong alkali.

Application: Used for NR, IR, SBR, NBR, EPDM and latex. Used as a secondary accelerator in combination with PZ and EZ. It has similar performance as MBT at curing temperature in dry rubber application. Has lower scorch and better processing safety. It is suitable for mold curing. Require zinc oxide and stearic acid as activators in many kinds of rubber batch. Easily disperses in rubber; yields non-staining and non-discoloring products. Mainly used in the manufacture of latex products, foam rubber, latex coating gloves etc, it will not affect the stability of latex.
Packing& Storage:
25kg N.W. /bag, in plastic fabric laminated kraft bags lined with plastic bags.
Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight.
