Characteristics
- CSIAO-245 is a hindered phenolic antioxidant with a three-dimensional structure especially suitable for organic substrates. It protects substrates from thermal oxidation during manufacturing, processing and through to the final product. CSIAO-245 exhibits odorless, low volatility, excellent discoloration resistance and high extraction resistance.
Application
- CSIAO-245 is a hindered phenolic antioxidant with high molecular weight that is effective in preventing oxidation by heat during the process from polymerization of various polymers to final products.
