The appearance of Sinanox® is white powder. Easily soluble in organic solvents such as benzene, chloroform, cyclohexane, etc., insoluble in polar solvents such as water and alcohol, and slightly soluble in esters. This product has low toxicity and good thermal stability. Excellent hydrolysis resistance. The uniqueness of Sinanox®-168 is that if the product is soaked in hot water at 90±1℃ for 14 hours, the product can still be fully recovered, and the quality will not be affected. This product is generally not used alone. It is often used in combination with the antioxidant Sinanox®-1010, Sinanox®-1076 and other phenolic main antioxidants to improve the stability of polymer materials during thermal processing.
