  Properties:Gray-white or light yellow powder (granule) with a little bitter,no poison. The density is 1.45-1.54 Soluble in chloroform, partly soluble in benzene, ethanol, CCl₄, insoluble in gasoline, water and ethyl acetate. Good storage stability.

  Application: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 WILLING MBT

  Packaging:20kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bag

  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
