Chemical name: dipentamethylene thiuramhexasulfide molecular formula: c12h20n2s8 molecular weight: 448.77 cas no: 971-15-3 properties: light yellow powder (granule). No taste, no poison. The density is 1.5. Soluble in chloroform, benzene, acetone, cs2, partly soluble in gasoline and ccl4 insoluble in water and alkali of lower concentration application: secondary accelerator for nr, sbr, epdm, and nbr. For rich sulphur content of 28%, it could be used as cure agent. In the system of sbr and nbr, it could be used the primary cure agent. No poison and no pollution. Easily dispersed in rubber system 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 ventilationavoiding exposure of the packaged product to direct sunlight. The validity is 2 years

Rubber accelerator zdc (zdec, ez) chemical name: zinc diethyl dithiocarbamate molecular formula: c10h20n2s4zn molecular weight: 361.9 cas no: 14324-55-1 properties: white powder (granule). Density is 1.41. Soluble in 1% naoh solution, cs2, benzene, chloroform, slightly soluble in alcohol, insoluble in gasoline application: used for nr, ir, sr, sbr, nbr, epdm and their latexes. A fast curing primary or secondary effective ultra-accelerator for natural and synthetic latex form compounds. Can be used advantageously for dipped, spread, and cast goods. Similar in property that of willing pz. Less resistance to scorching than willing pz and shows a slight tendency to premature vulcanization. An antioxidant in adhesive systems 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.

Rubber accelerator zmbt(mz) chemical name: zinc 2-mercaptobenzothiazole molecular formula: c14h8n2s4zn molecular weight: 397.86 cas no: 155-04-4 properties: light yellow powder (granule) with a little bitter, no poison. The density is 1.70, the decomposable temperature is 300î¿c. Soluble in chloroform, acetone, partly soluble in benzene, ethanol, ccl4, 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. May be regarded as an intermediate between willing m and willing dm. Used as a secondary accelerator in combination with willing pz andwilling ez. Similar performance as willing 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; yields non-staining and non-discoloring products. Mainly used in the manufacture of latex products, foam rubber, latex coating gloves, etc packaging: 25kg 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.
