Property: Dark green powder with a density of 1.26g/cm3. Melting point above 86 ℃. Flash point 263 ℃. Soluble in chloroform, benzene, carbon disulfide, slightly soluble in acetone, insoluble in water. Good stability during storage period. Toxic, has a irritating effect on the skin, and inhalation of steam and dust is harmful to the human body.

Usage: Rubber or plastic antioxidant. Mainly used in synthetic rubbers such as styrene butadiene, chloroprene, and chlorosulfonated polyethylene, it can prevent rubber cracking caused by sunlight and ozone, and improve the heat resistance of chloroprene rubber and chlorosulfonated polyethylene. Used as a light stabilizer and ozone resistant agent for polymer materials in the plastic industry. Used in polypropylene fibers, thin films, and narrow bands, it has excellent photostability, but causes the product to have a yellow green color. The general dosage is 0.3~0.5%.

Packaging: kraft paper bag, net weight 25 kilograms.
