Rubber Accelerator MBT(M): Identification: Chemical Name: 2-Mercaptobenzothiazole Synonym: Sulfur Accelerator M; 2-MBT; Benzothiazole-2-thiol CAS NO.: 149-30-4 Structural Formula: Molecular Formula: C7H5NS2 Properties: It is light yellow powder (granule) with a little osmyl and taste bitter. The density is 1.42-1.52 Soluble in ethyl acetate, ethanol, solution of NaOH and Na2C03, insoluble in benzene, water and gasoline. Good storage stability. lower explosion limit is 21g/m3. Specification: Item Powder Oiled powder Granule Appearance Light yellow powder(granule) Initial M.P. ℃ ≥ 171.0 171.0 171.0 Loss on drying % ≤ 0.30 0.50 0.30 Ash % ≤ 0.30 0.30 0.30 Residue on 150μm sieve % ≤ 0.10 0.10 \ Granule Diameter mm \ \ 1.0-3.0 Application: Used as an acid accelerator currently and a medium fast primary accelerator. Imparts excellent aging properties when used both alone and in combination with DM, TMTD and many other basic accelerators for higher activity. Its accelerative temperature is low and easily be dispersed with lower pollution. Mainly used in the manufacture of tires, tubes, foot wear, rubber belts and hoses etc,can not be used as food material. Packing& Storage: 25kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bag. Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 2 years when stored under normal conditions.
