What is Antioxidant 168 with CAS 31570-04-4?
Antioxidant 168 is an excellent phosphate ester antioxidant with a white powder appearance. It is easily soluble in organic solvents such as benzene, chloroform, and cyclohexane, slightly soluble in ethanol and acetone, insoluble in polar solvents such as water and alcohol, and slightly soluble in esters. Low toxicity, low volatility, high thermal stability, excellent hydrolysis resistance, and effective decomposition of hydroperoxides generated during thermal processing of polymer materials.
