Polymers are prone to oxidation, during the processing steps (compounding/ pelletizing, fabrication and recycling) from molecular weight change (e.g. chain scission/crosslinking). To prevent the oxidation of Polymers during the processing and extrution, antioxidant chemicals are added. KAPL is an antioxidants manufacturer. Antioxidants are of two types – Primary and Secondary. These protects the polymers from getting oxidized and prevents polymer discoloration. As a secondary antioxidant, it reacts during processing with hydroperoxides formed by autoxidation of polymers preventing process induced degradation and extending the performance of primary antioxidants.
