Properties: Yellow powder. The loosen density is approx 0.32-0.36g/cm3 . Soluble in chloroform, benzene, and carbon disulfide, slightly soluble in alcohol and gasoline, insoluble in water.
Uses: As a super accelerator used in natural rubber, styrene-butadiene rubber. Commonly, used with some other kinds of accelerators such as benzothiazole, sulfenamide. A fast velocity at vulcanizing temperature can be obtained, and intensile can be increased. Suitable for making inner tube of tires, soft tube, isolating layer of wire and cable, etc. It’s not suitable for the products contacting with foods. TDEC is not regulated for use in articles in contact with food.
