Applications

• RIANOX® 686 is a hydrolytically stable phosphite processing stabilizer. As a secondary antioxidant, RIANOX® 686 reacts during processing with hydroperoxides formed by autoxidation of polymers preventing process induced degradation and extending the performance of primary antioxidants.
• The application range of RIANOX® 686 comprises engineering plastic, such as PA, PC, polyester, etc.
• Typically, 500 - 2000 ppm of RIANOX® 686 combined with appropriate levels of other additives are used for the processing stabilization of polymers.
