Product Description

Accelerator M:Chemical name: 2-mercaptol benzothiazole, mbt for shortBasic performanceThe chemical name of accelerator M is 2-Mercaptobenzothiazole, abbreviated as MBT, and the molecular weight is 167.25. Light yellow monoclinic acicular or flaky crystalline powder, slightly smelly and bitter, with a relative density of 1.42. Melting point: 170 ~ 181 ºC. It is dissolved in acetone, ethyl acetate, dichloromethane, ethanol, and alkaline solutions such as sodium hydroxide and sodium carbonate. Slightly soluble in benzene, insoluble in water and gasoline. It is combustible and may explode when it is in the form of dust. Low toxicity, LD50 5000mg / kg.character:Light yellow powder (particle), slightly smelly, bitter, non-toxic, specific gravity 1.42-1.52, melting point 170-181 ºC, easily soluble in dilute solutions of ethyl acetate, acetone, sodium hydroxide and sodium carbonate, soluble in ethanol, insoluble in benzene, insoluble in water and gasoline. It is combustible and stable in storage. In case of dust, the lower explosion limit is 21g / m3. Low toxicity, LD50 5000mg / kg.Purpose:For IR, NR, SBR, NBR, HR and EPOM systems, it is a major acidic vulcanizing agent with medium vulcanization speed. When combined with other vulcanizing agents such as willling DM and willling TMTD, it can achieve higher activity. Its vulcanization temperature is low, it is easy to disperse in rubber, and it is not polluted. It is mainly used for manufacturing tires, tapes, rubber shoes and other industrial rubber products, but it can not be used as food materials. Technical indicators:
