Properties: Grey or light yellow in color with bitter taste and slight odor. Specific gravity: 1.26-1.32, Soluble in ethanol, carbon tetrachloride, acetone, benzene, carbon disulfate, chloroform; Hardly soluble in gasoline and insoluble in water. It is not hygroscopic.
Application: Provides fast cure and high modulus development in NR,SBR,BR,IR,NBR & EPDM. The features of the product include heat-resistance and long cure time, which makes it suitable for boiler smelting. It is widely applied in various kinds of rubbers such as NR, IR,SBR,NBR, etc. It is also hear-resistant and has a slight scorch improvement. This produce can be applied alone, but mostly with accelerators of thiurams & dithiocarbamates. It is mainly used in the manufactures of tires belts, rubber pipes TBBS may give high modulus. Because of the bitterness of the product after vulcanization, it is not recommended to apply it to beverage and food containers. It causes little pollution and can be used in light-colored products.
Package: 25kg/ N.W./bag , in plastic fabric laminated Kraft bags lined with plastic bags
Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 1 year when stored under normal conditions.
