Product name: ANTIOXIDANT 168 CAS NO: 31570-04-4 Molecular formula : C42H63O3P Molecular weight : 646 Structural formula : SPECIFICATION: Item Standard Appearance White powder Melting range °C 183-187 Volatile % ≤ 0.3 Solubility Limpidity Light Transmittance % ≥ 425nm 98 500nm 98 Acid Number (mgKOH/g) % ≤ 0.3 Anti-hydrolyze(90°C, water,14h) Qualified 2,4- t-butyl-phenol % ≤ 0.2 Purity % ≥ 99 Typical properties: Easily soluble in such organic solvents as benzene ,chloroform ,cyolohexane and so on ; slightly soluble inesters,but insoluble in polar solvents, such as water, alcohols and so on. Low toxicity, good thermostability, non-hydrolyzable, etc.The peculiarity of the product(is that it)can all be retrieved if soaking in the hot water at 90±1°C within 14 hours and its quality will not be affected. Applications: RA-168 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. RA-168, usually not used alone, is compounded with hindered phenolic primary antioxidants, such as JY-10, to improve thermostability of polymer during the processing. There are over ten kinds of blends of JY-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. Packing: 25kg.net bag Storage and transportation: in cool, ventilated and dry place
