It is easily soluble in such organic solvents as benzene, chloroform, cyolohexane etc., slightly 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.
Applications:
It is a secondary antioxidant with excellent resistance to extraction by water, low volatility and high heat stability. 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 1010,1076, to improve thermostability of polymer during the processing. There are over ten kinds of blends of 168 with phenolic antioxidants, widely used in the polymer materials, such as polylefins ( eg. Polyethylene, polypropylene etc.), polyamide, polycarbornate, ABS and so on. The product is used for general chemicals only, not as food additive.
Storage:
Stable in property. No special requirement but keep away from damp or heat.
Packing:
Net weight 25kg bags or cartons. It can also be designed according to customers' requirements.
