从China供应商批发进口2-Mercaptobenzothiazole — FOB条款

2-Mercaptobenzothiazole (MBT), identified by CAS No. 149-30-4, is a primary rubber vulcanization accelerator supplied by Henan Kailun Chemical Co., Ltd from China. This material conforms to the Chinese executive standard GB/T 11407-2003 and is supplied as a light yellow or greyish-white powder or granules. Its key specifications include an initial melting point of at least 170.0°C, a loss on drying of 0.30%, and an ash content of 0.30%.

The product has a molecular weight of 167.26 g/mol and a density typically between 1.42 and 1.52 g/cm³. It demonstrates good storage stability with a recommended shelf life of two years under normal conditions. MBT is soluble in ethyl acetate, ethanol, and alkaline solutions like NaOH, while being slightly soluble in benzene and insoluble in water and gasoline. Its lower explosion limit is 21 g/m³, a standard safety parameter for this chemical.

As an acid accelerator with medium-fast activity, MBT is a workhorse chemical in the rubber industry, primarily for manufacturing tires, inner tubes, footwear, rubber belts, and hoses. It imparts excellent aging properties when used alone or in combination with other accelerators like DM and TMTD. Henan Kailun Chemical packages it in 25 kg plastic woven bags, paper with plastic film bags, or kraft paper bags. Buyers should confirm specific packaging options and whether ultra-fine powder grades are available to meet their formulation needs.
