Performance:The relative density is 1.048, the boiling point is 257~265 ℃, and the flash point is 126.6 ℃. Soluble in benzene, toluene, propanol, ketone, carbon tetrachloride, ethyl acetate and gasoline, insoluble in water and dilute caustic soda solution. This product is non-toxic, in the case of light storage will gradually deteriorate, affecting the use of results.
Use:This product is an excellent non-pollution antioxidant. Used as styrene-butadiene, isoprene, nitrile, chloroprene and other synthetic rubber thermal oxygen aging protection, light aging and copper protection, used in the manufacture of white, bright color, light color, transparent rubber products (such as rubber shoes, tape products). Easily dispersed in the rubber, can be directly mixed into the rubber, can also be made into a dispersion for latex products. Due to its low toxicity, food grade 264 can also be used in the medical and health and food processing industries. In the petroleum industry, it is an excellent antioxidant for various lubricating oils, secondary processing gasoline, paraffin and other mineral oils. It is an antioxidant for polypropylene, polystyrene, ABS resin, polyester, cellulose resin and foam plastic.
Packing:Composite paper bag, lined with plastic film bag, net weight 25kg.
Storage:Sealed and stored in a cool, dry, well-ventilated place, away from direct sunlight.
Safety and Toxicity:Please refer to the relevant product safety data (MSDS).
