It is easily soluble in such organic solvents as benzene, chloroform,etc.,soluble in esters, but not in polar solvents, such as water, alcohols etc. Low toxicity, good thermostability, non-hydrolyzable, etc. The peculiarity is that it can all be retrieved if soaking in the hot water at 90±1℃ within 14 hours and its quality will not be affected.
It can effectively decompose hydroperoxides produced during the processing of polymeric materials. It isn't usually used alone, compounded with hindered phenolic primary antioxidants such as Antioxidant-1010, to improveof polymer during the processing. There are over ten kinds of blends of Antioxidant-168 with phenolic antioxidants, widely used in the polymer materials, such as(eg. Polyethylene, polypropylene etc.), polyamide,, ABS and so on. The product haseffectHALS.
