Product Overview
Specificationi Chemical Analysis: Product Name : Rubber Accelerator NOBS(MBS) Chemical Name : N-Oxydiethylene-2-benzothiazole sulfonamide CAS NO. : 102-77-2 Molecular Formula : C11H12N2S2O Molecular Weight : 253.35 Appearance (visual inspection): Light yellow granule Assay Content %A : 95 Initial M.P. AY: 80.0 Loss on drying (%)a : 0.50 Ash content (%)a : 0.30 Insoluble in methanol %a : 0.50 Strength of grain(N) : 0.8-2.5 Bulk density (kg/m3): 340-380 Typical Properties:- Light yellow granule with little odor of ammonia, no poison. The density is 1.31-1.34.The melting point is more than 78AY. It soluble in chloroform, benzene, Acetone. Insoluble in water, gasoline, acid / alkali with lower concentration. It will decompose step by step with temperature over 60AY. Recommended Applications:- It can be used as sole accelerator or in combination with low level of secondary accelerators in NR or Synthetic rubber compounds where extended scorch time are required. Typical examples are thick tire treads and extrusion, compounds with high loading of furnace blacks and compounds which are stored, uncured, for long periods, such as camelback.
