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 gasoline, benzene, acetone, ethyl acetate, dichloromethane, carbon tetrachloride ,methylbenzene, ethyl alcohol and other organic solvents, insoluble in water.
Application:
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 or manganese 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, and also can be used as heat oxygen stabilizer for polyethylene, polypropylene and acrylic resin.
Packaging and storage:
1. In woven bag or paper bag lined with PE film bag, net weight: 25Kg/bag.
2. Stored in dry, clean and cool warehouse, Shelf life is one year.
