ADEKA ADK STAB AO-80 (CAS 90498-90-1) Semi-Hindered Phenolic Antioxidant for Plastics

Basic Chemical Information • Model: ADK STAB AO-80 • CAS Number: 90498-90-1• Chemical Name: 3, 9-bis [1, 1-dimethyl-2 -[(3-tert-butyl-4-hydroxy-5-methylphenyl) propoxyloxy] ethyl]-2,4,8, 10-tetraoxane [5.5] undecane • Category: Semi-hindered phenolic main antioxidant (spiro Special structure) • Molecular weight: 741• Appearance: Pure white fine powder • Melting point range: 110-125℃• Active ingredient content: ≥98%• Original factory packaging: 20kg kraft paper bag (the same style as your poster), original imported from Japan.  Basic physical properties • Low volatility: It is not easy to volatilize during high-temperature extrusion and injection molding, and is not prone to blooming. • Hydrolysis resistance: Its stability in humid processing environments is far superior to that of common 1010 antioxidant (AO-60RG). • High compatibility: It has strong compatibility with plastics, rubber, and elastomers, and does not affect the transparency of the products. Top-notch anti-fumigation discoloration in the industry:Common hindered phenolic antioxidants will cause powdering, redness and yellowing when in contact with boiler exhaust gas and combustion exhaust gas (NO <s:1> nitrogen oxides); The special screw ring structure of AO-80 can significantly suppress NOx gas fumigation and fading, making it suitable for films, fibers, light-colored injection molded parts, and plastic products that are placed indoors for a long time. Dual thermal oxygen protection 1) Processing stability: The high-temperature melting process captures free radicals, preventing melt breakage, yellowing, and fluidity decline; 2) Long-lasting aging resistance: The product does not become brittle and its mechanical strength does not decline even after long-term high-temperature use. Excellent synergistic compounding effect • Combined with phosphite ester auxiliary antioxidant: Enhanced processing anti-yellowing, suitable for transparent plastics; • Combined with sulfide antioxidants: Long-lasting heat aging resistance doubles, preferred for automobiles and high-temperature pipes; • Combined with light stabilizers: The weather resistance of outdoor products is significantly enhanced. Food contact compliance has passed the FDA of the United States, REACH of the European Union, and food hygiene certifications of Japan. It can be used for food packaging films, lunch boxes, and food-grade pipes, with no toxic emissions. 5. Low migration, resistant to extraction, not easily extracted by oil, water or solvents, suitable for plastic products (hoses, food containers, inks) that come into contact with oils and liquids.
