Thermal Loading and Oxidation

Common stabilizers for organic cellulose molding compounds include epoxides, especially epoxidized soybean oil, alkaline and alkaline-earth salts of acetic and carbonic acid as well as tartaric acid, oxalic acid and citric acid. Effective antioxidants include substituted phenols, such as t-butylphenol, or preferably sterically hindered phenols, such as 2,6-di-tert-butyl-p-cresol. Diphenylamine or esters of thiopropionic acid exhibit an effect similar to that of antioxidants [501]. 

Only cellulose acetobutyrate and, to a limited degree, cellulose propionate molding compounds can be effectively equipped with weathering stabiiizers. For ceiiuiose diacetate molding compounds, no climate stabiiizer has yet been found that maintains serviceability even after years of outdoor weathering.
