Properties: White powder (granule). No taste, no poison. Density is 1.66. Soluble in lower concentration alkali, CS2, benzene, acetone and CH2Cl2, partly soluble in chloroform, insoluble in alcohol, CCl4 and ethyl acetate.

Application: Used for NR, IR, BR, SBR, NBR, HR, EPDM and natural & synthetic latexes. Stronger accelerating power than TMTD. Strong resistance to scorching. In its handling, care should be operated, because of its increase activation and strong tendency to scorch at low temperatures (100οC). Often used as a secondary accelerator. In latex, better results are obtained when used in combination with other types such as thiazole accelerators. Used for rubber coated fabrics, latex products and rubber cement, etc. FDA approved in USA.

Packaging: 25kg plastic woven bag, paper with plastic film bag, kraft paper 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.
