Chemical Name: 2-Mercapto benzimidazole Molecular Formula:C7H6N2S Molecular Weight: 150.19 CAS NO: 583-39-1
Chemical Name: Tetramethyl thiuram disulfide Molecular Formula: C6H12N2S4 Properties: White or light gray powder (granule). The density is 1.29. Soluble in benzene, acetone, chloroform, CS2 partly soluble in alcohol, diethyl ether, CCI4 insoluble in water, gasoline and alkali with lower concentration. Meeting hot water becomes to dimethyl ammonium and CS2. Be sensitive to skin and peogaster Application: Can be used as a single accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers. Scorchy and gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging and compression set resistance in sulphurless and EV cure systems Good color retention is obtained in non-black vulcanisation. A valuable secondary accelerator for EPDM. May be used as a retarder in the vulcanisation of polychloroprene rubber with ETU and also be used as bactericide and pesticide 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.
Chemical Name: N-Tertiarybutyl-2-benzothiazole sulfenamide Molecular Formula:C11H14N2S2 Molecular Weight:238.37 Quality standrad:HG/T2744-96 CAS NO:95-31-8 Properties: Gray white powder (granule). The density is 1.26-1.32. soluble in benzene, CS2, methyl alcohol, acetone. chloroform, alcohol, insoluble in gasoline, water, acid and alkali with lower concentration Application: Provides fast cure rate and high modulus development in NR, SBR, BR and blends. Normally used alone or with small quantities of ultra accelerators in tire compounds or industrial rubber products low poison and high efficiency. It is good back up for NOBS. Be regarded as standard accelerator 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 1 year.
Chemical Name:N-Cyclohexyl-2-benzothiazole sulfenamide Molecular Formula:C13H16N2S2 Molecular Weight:264.4 CAS NO:95-33-0 Properties: Gray-white powder (granule) with a little odor, no poison. The density is 1.31-1.34. Soluble in benzene,boluene, chloroform, CS2, CH2Cl2 acetone, ethyl acetate, hardly soluble in alcohol, insoluble in water,gasoline, acid / alkali with lower concentration. Application: A medium fast primary accelerator suitable for NR, IR, SBR, NBR, HR and EPDM. An outstanding delayed action accelerator. Be top effective and safe when used at ordinary processing temperatures, causing no scorches. Vulcanized show excellent physical property and quick complete. Usually used alone when activated by DPG, TMTD and TS. 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 1 year.
Chemical Name:2-Mercaptobenzothiazole Molecular Formula: C7H5NS2 Modular Weight: 167.25 CAS NO: 149-30-4 Properties: Slightly foul odor and bitter taste, nonpoisonous. Specific gravity: 1.46-1.52.Soluble in ethyl acetone, acetone, dilute solution of sodium hydroxide and sodium carbonate, ethyl alcohol. Not easily soluble in benzene. Insoluble in water and gasoline. Application: Used for NR, IR, SBR, NBR, HR and EPDM.One of the mainly used acidic accelerators currontly and a medium fast primary accelerator. Imparts excellent aging properties, when used both alone and in combination with DM,TMTD and many others, mainly basic accelerators for higher activity. But care should be taken because it has a slight tendency to scorch. Unsuitable for use in the manufacture of food contact materials. Mainly used in the manufacture of tires, tubes, footwear, rubber belts and hoses etc. Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 2 years when stored under normal conditions. Packaging:25kg bag.
Chemical Name: Dibenzothiazole disulfide Molecular Formula:C14H8N2S4 Properties: A little bitter taste. Specific gravity: 1.50--1.59. Soluble in chloroform, toluene, benzene, carbon tetrachloride. Insoluble in water and ethyl alcohol. Application: Given flat, moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber. Non-staining/non-discolouring in "white" socks; use as a plasticiser and/or retarder in polychloroprene rubber. Secondary acceleration is usually required for synthetic polymers. Better scorch safety than MBT. Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 2 years when stored under normal conditions. Packaging: 25kg bag.
