Chloroform, alcohol, insoluble in gasoline, water, acid and alkali with lower concentration. Usage: 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’s good back up for NOBS. Be regarded as standard accelerator 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.
Sodium- MBT (Na MBT)
Mainly used in the manufacture of tires, tape, rubber shoes and other industrial rubber products. This product is the rubber industry universal type accelerator, has the quick vulcanization function to the natural glue and the general sulfur vulcanization synthetic glue. In natural gum and styrene butadiene latex as promoter of dithiocarbamate. Easy to disperse in rubber, no pollution, suitable for natural vulcanized rubber paste and hot water vulcanized products. The solution made of water and alcohol can be used as corrosion inhibitor for steel, copper and aluminum products. Storage Storage for six months in dry and cooling place.
Rubber Accelerator-MBT (M)
Chemical Name: 2-Mercaptobenzothiazole Structure: Molecular Formula: C7H5NS2 Molecular weight: 167.26 CAS NO: 149-30-4
Rubber Accelerator-ZDBC (BZ)
Product properties & Features: White powder (granule) .The density is 1.24. Soluble in cS2. Benzene, chloroform, alcohol, diethyl ether, insoluble in water and low concentration alkali. Good storage stability Usage: Used for primary or secondary ultra-accelerator in NR，IR，BR，SBR，NBR，HR，EPDM, and their latexes. Similar in property to PZ and EZ. Less accelerating effects than PZ and EZ to dry rubber. Effectively used in both natural and synthetic latexes for faster curing at normal (low) temperature than with PZ and EZ, and less scorching and blooming 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 year.
Rubber Accelerator- MB (MBI)
Properties: White powder. No smell but taste bitter. The density is 1.42.Soluble in alcohol acetone, ethyl acetate, slightly soluble in petroleum ether. CH2Cl2.，CCl4，benzene and water. Good stabilization storage ability. Application It is used as antioxidant for natural rubber and latex; also used to for polyethylene. It can be used alone or together with other anti-aging agent (such as DNP, AP and other nonpolluting anti-agers). It should not be used for food contact rubber products. Storage The product should be storage in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 2 years.
Product properties & Features: Zinc stearate is a fine white powder with smooth handle, no sandy feeling, fat odor, easy to absorb moisture, non-toxic, slippery flammable, insoluble in water, soluble in hot ethanol, turpentine benzene and other organic solvents. Decomposition of strong acid into stearic acid and corresponding zinc salts Usage: 1).it is used in the processing of non-toxic PVC products, and has synergistic effect with calcium stearate and barium stearate. 2).It can effectively improve the light stability of PVC products. The dosage in the processing of PVC is usually less than one part 3).It is also used in the manufacture of rubber products touch agent, and also used in the manufacture of several pencil cores of PP, PE, PS, EPS polymerization additives, with the general dosage of 1-3 parts.
