ALKANOX™ 240 Granular is an organo-phosphite antioxidant and stabilizer, similar to ALKANOX™ 240 Powder but supplied in a non-dusting granular form.

ALKANOX™ 240 Powder is low-volatility and thermally stable organophosphate antioxidant that prevents oxidative degradation for a variety of polymers.

ANOX™ 20 Granular is a high–molecular weight hindered primary phenolic antioxidant. It prevents polymer degradation during long-term aging in various polymer systems.

ANOX™ 20 Powder is a high molecular weight hindered phenolic primary antioxidant. Effective as a process stabilizer, but is especially powerful at preventing polymer degradation during long-term aging.

ANOX™ PP18 Powder is a high–molecular weight hindered phenolic antioxidant that effectively protects against polymer degradation during processing and long-term aging.

LOWINOX™ 1790 provides excellent gas-fading resistance and low load levels. It is especially effective in polyurethane, PP, PE, and nylon fibers.

NAUGARD™ 445 Granular is an excellent-performance amine antioxidant with significant synergy with phenolics, particularly effective in extreme heat and oxygen environments.

NAUGARD™ 445 Powder is an amine antioxidant with excellent synergy with phenolic antioxidants and excellent for use in extreme heat and oxygen environments.

ULTRANOX™ 626 is a high performance solid phosphite antioxidant that improves color stability and reduces polymer degradation during compounding, fabrication, and end use in a variety of resins.

ULTRANOX™ 626A is a high performance solid phosphite antioxidant that improves color stability and reduces polymer degradation during compounding, fabrication, and end use in a variety of resins. Similar to ULTRANOX^® 626 but in a granular form.

ULTRANOX™ 627AV is a high performance solid phosphite antioxidant that improves color stability and reduces polymer degradation during compounding, fabrication, and end use in a variety of resins. Similar to ULTRANOX™ 626 but in a free-flowing form with an inorganic neutralizer for improved handling characteristics.
