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 ADDYAOT-1010,
to improve thermostability of polymer during the processing.
◾️ There are over ten kinds of blends of ADDYAOT-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.
Recommended Dosage :
0.1-0.3%
Storage :
Stable in property. No special repuirement but keep away from damp or heat.
Packing :
It is packed in cardboard box lined with plastic bags with the net capacity of 20 kg or It is packed in three-in-one
compound bags. The inner layer is plastic film and the outer is polypropylene braided lining kraft paper bags with the
net weight of 20kg. It can also be designed according to customers' requirements.
