Properties: Pure 6PPD is white solid product, and will gradually oxidizing to brown solid when exposed to the air. Industrial product—6PPD is purple brown to black brown granules or flakes, and will slowly caking When the temperature exceeds 35-40℃.Soluble in gasline, benzene, acetone, ethyl acetate, dichloroethane, carbon tetrachloride ,methylbenzene, ethylalcohol and other organic solvents, insoluble in water.

Application: As a kind of ursol rubber antioxidant, 6PPD has better compatibility with rubbers, seldom blooming, low volatility, low toxicity, with excellent antioxidant, anti-ozone, anti-flex cracks , anti-insolation cracks, strong inhibition on copper ormanganese and other toxic metals, applicable to all types of synthetic rubber and natural rubber. With good dispensability in sizing material and little effect on vulcanization, It can soften sizing material, so can be used for tires and other kinds of rubber products, also can be used as heat oxygen stabilizer for polyethylene, polypropylene and acrylic resin.

Package : N.W. 20kg/bag, or N.W. 25Kg/bag, packed with kraft paper bag.
