Features: 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.
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 LP-1010, to improve thermostability of polymer during the processing. There are over ten kinds of blends of LP-168 with phenolic antioxidants, widely us in the polymer materials, such as polylefins (eg. Polyethylene, polypropylene etc.), polyamide, polycarbornate, ABS and so on. The product has good effect with HALS.
Storage: Stable in property. No special repuirement but keep away from damp or heat.
Packing: Net weight 20kg bags or cartons.It can also be designed according to customers' requirements.
