Introduction:

 

Antioxidant 168 is an excellent phosphite antioxidant with strong resistance to extraction, stable hydrolysis, and can significantly improve the light stability of products, and can be used in combination with a variety of phenolic antioxidants. For example, Cyanox2777 developed by Cyanamid in the United States is a compound of antioxidant 168 and phenolic antioxidant 1790.The combination of phosphite and phenolic antioxidants can give full play to the synergistic effect. The phosphite in the component is an auxiliary antioxidant, which cannot play a long-term stabilizing role. However, after the mixture of phosphite and hindered phenol, a better compound effect is obtained, which can be used in a variety of polymers.

 

Feature

 

It is easily soluble in such organic solvents as benzene, chloroform, cyolohexane etc., sightly 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.

 

Application
   

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 improve thermostability of 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 polylefins (eg. Polyethylene, polypropylene etc.), polyamide, polycarbornate, ABS and so on. The product has good effect with HALS.
