Properties:
Pure 6PPD is white solid product, will gradually oxidizing to brown solid when exposed to the air. Industrial product—6PPD is purple brown to black brown granules flakes, will slowly caking When the temperature exceeds 35-40℃.Soluble in gasline, benzene, acetone, ethyl acetate,dichloroethane, carbon tetrachloride ,methylbenzene, ethylalcohol otherganic 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 coppermanganese other toxic metals, applicable to all types of synthetic rubber natural rubber. With good dispensability in sizing material little effect on vulcanization, It can soften sizing material, so can be used ftires other kinds of rubber products, also can be used as heat oxygen stabilizer fpolyethylene, polypropylene acrylic resin.
