Rubber Accelerator MBTS(DM) Chemical Name: Mercaptobenzothiazole disulfide structure: CAS NO: 120-78-5 Molecular Formula: C14H8N2S4 Molecular Weight: 332.50 Specification: Item Powder Oiled powder Granule Appearance Gray-white or light yellow powder(granule) Initial M.P. ℃ ≥ 170.0 170.0 170.0 Loss on drying % ≤ 0.30 0.50 0.30 Ash % ≤ 0.30 0.30 0.30 Residue on 150μm sieve % ≤ 0.10 0.10 \ Residue on 63μm sieve % ≤ 0.50 0.50 \ Additive % \ 1.0-2.0 \ Granule Diameter mm \ \ 1.50 Properties: Gray-white or light yellow powder (granule) with a little bitter,no poison. The density is 1.45-1.54 Soluble in chloroform, partly soluble in benzene, ethanol, CCl4, insoluble in gasoline, water and ethyl acetate. Good storage stability. Application: Given flat, moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber. Non-staining and non-discolouring in "white" socks; used as a plasticizer and retarder in polychloroethylene rubber. Secondary acceleration is usually required for synthetic polymers. Better scorch safety than WILLING MBT Packaging: 20kg 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.
