RUBBER CHEMICALS. PRODUCT. Application. TMTD Tetramethyl thiuram disulfide. TMTD is used as a primary and secondary accelerator or as a sulfur donor (vulcanizing agent) in most sulfur-cured lastomers in rubber industry. MBT 2 Mercaptobenzothiazole: Medium-speed accelerator with a very wide range of applications.
Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly aC (doublet the C = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C

MBT is widely used in industry and in household articles. MBT is primarily used in the rubber industry as a non-volatile vulcanisation accelerator. MBT is also used as an intermediate in the production of other accelerators, some of which may decompose during vulcanisation and form MBT (BUA 1997).

China MBTS Manufacturer, Suppliers, Factory Rubber
2-Mercaptobenzothiazole (MBT) and 2,2'-dithiodibenzothiazole (MBTS) are the core products of rubber vulcanization accelerators. The production process uses a high temperature and high pressure reaction environment. The system is highly toxic and corrosive. The conventional production process uses a batch reactor, and a production capacity of
Select Accelerators for Rubbers. Edward M. Petrie. Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. Selection of an accelerator will depend on the specific vulcanizing system and curing properties.
