Product Name: NOBS (MBS) Chemical Name: N-Oxydienthylene-2-benzothiazole sulfenamide Molecular Formula: C11H12N2S2O Type Name: FC-NOBS-/A/B CAS Number: 102-77-2 Specification: Grade A B Appearance yellow granule Melting Point C min. 80. 0 78. 0 Heating Lost % max. 0. 50 0. 50 Ash % max. 0. 30 0. 40 Sieve Residue (150 um ) % max. 0. 05 0. 1 Property: Light yellow or brownish granule, bitter tasting. Specific gravity: 1. 34--1. 40. It is soluble in benzene, acetone, methyl alcohol; But insoluble in water. Application: An excellent delayed accelerator. It performances similar as CBS(CZ) but with better scorching resistance. It can be used solely or together with those accelerants such as thiurams, guanidines and dithiocarbamates, joining with other accelerants will improve its reactive activity. It is mainly used in NR, IR, SBR, NBR and EPDM to manufacture tires, shoes, belts & etc. Non-flaming. Not suitable applying in beverage and food containers because of the bitterness of the product after vulcanization. Packaging: 25kg per plastic woven bag. Storage: In a low temperature condition, keeping away from heat and moisture to prevent from degradation reaction. The proper storage time is in 24 months.
