IRGANOX® 245 DW is a 40% active aqueous dispersion of IRGANOX 245, a sterically hindered phenolic antioxidant. It protects the substrates against thermo-oxidative degradation during manufacturing, processing and end-use.

This product is recommended particularly for the stabilization of polyvinyl chloride (PVC). In addition to imparting themostability to the finished polymer, IRGANOX 245 DW is effective as chain stopped during PVC polymerization.

The desired quantity of IRGANOX 245 DW can easily be added or dosed into the polymerization system. As the antioxidant is uniformly dispersed in the reaction mixture, the resulting PVC chloride develops improved qualities such as excellent heat stability, low color and high thermal stability. The formation of fish eyes in film applications can also be reduced considerably. Additionally, IRGANOX 245 DW imparts excellent chain terminating properties during PVC polymerization.
