Properties: white or light yellow powder (granule) with a little bitter, no poison. The density is 1.50, Melting point above 170℃,slightly soluble in benzene, chloroform and ethanol, is not soluble in water petrol. And ethyl acetate. Good storage stability.

Usage:

It is used to be given flat, moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber. Non-staining and non-discolouring in "white" socks; used as a plasticizer and retarder in polychloroethylene rubber. Secondary acceleration is usually required for synthetic polymers. Better scorch safety than MBT.

Storage:

The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 2 years.
