rubber accelerator CBS/CZ

Accelerator CBS(CZ) Chemical Name N-Cyclohexyl-2-benzothiazole sulfonamide Molecular Formula C13H16N2S2 Molecular Weight 264.4 Gravity 1.31-1.34 CAS NO. 95-33-0 Specification Powder Oil-coated Powder Granule Grayish White Initial M.P. ℃≥ 98.0 98.0 98.0 Loss on Drying %≤ 0.30 0.30 0.30 Ash %≤ 0.30 0.30 0.30 Free Amine %≤ 0.50 0.50 0.50 Assay%≥ 96.0 96.0 96.0 Residues(150μm) % ≤ 0.10 0.10 -- Oil Content % -- 1.0-2.0 -- Properties: Soluble in benzene, dichloromethane, carbon tetrachloride, ethyl acetate, acetone, slightly soluble in ethanol and petrol. Insoluble in water. Uses: This is a delayed accelerator, with good anti-scorching quality, as well as short vulcanizing duration, which would improve the tensile stress of vulcanization. Minor discoloration, no blooming, antioxidant quality of vulcanization is superior. When applied, adding zinc oxide and stearic acid are necessary to strengthen the effect of TMTD, TMTM, ZDMC, DPG or other alkaline accelerators that are used as second accelerator, as well as being activated by MBT and MBTS. Package 25kg/bag Storage Life 24 months
