PROPERTIES:


Light yellow powder/granule, with a little bitter, no poison. The density is 1.70. Decomposable temperature is 300℃.
Soluble in chloroform, acetone, partly soluble in benzene, ethanol, CCI4. Insoluble in gasoline, water and ethyl acetate. Decomposion when meeting strong acid and strong alkali.

APPLICATION:


Used for NR, IR, SBR, NBR, EPDM and latex. As a secondary accelerator in combination with PZ and EZ. Similar performance as MBT at curing temperature in dry rubber application.
Has lower scorch and better processing safety. Suitable for mold curing. Require zinc oxide and stearic acid as activators in many kinds of rubber batch.
Easily disperses in rubber, yield non-staining and non-discoloring products. Mainly used in the manufacture of latex products, foam rubber, latex coating gloves, etc.
