BIONOX 245 is a high molecular weight hindered phenolic antioxidant that provides very low volatility and excellent resistance to extraction from polymer compounds.

Primary antioxidant for organic polymers.
High performance sterically hindered phenolic antioxidant that protects the polymer against thermo-oxidative degradation during the manufacturing processes and in end-use applications.

An effective antioxidant for styrenics, synthetic rubbers, POM homo & copolymer, polyurethanes, polyamides, polyesters, MBS and PVC.
Low volatility, good color stability, and extraction resistant.
Chain Stopper in PVC and ABS manufacturing process.
Fish Eye reduction in flex-PVC applications.
Can be used with benzotriazoles or HALS for thermal and light stabilization in outdoor use.
Exhibits a synergistic effect when used in combination with thioester antioxidants.
