Product Introduction

Antioxidant 2246 is a high-efficiency sterically hindered phenolic primary antioxidant widely used in rubber, plastics, latex, petroleum products, elastomers, and industrial material formulations.

Chemically known as 2,2′-Methylenebis(4-methyl-6-tert-butylphenol), Antioxidant 2246 is designed to provide protection against thermal oxidation, oxygen aging, processing degradation, and long-term oxidative deterioration in organic materials.

Due to its non-staining characteristics, strong antioxidative performance, and suitability for light-colored materials, Antioxidant 2246 is widely applied in natural rubber, synthetic rubber, latex products, ABS resin, polyethylene, and specialty polymer stabilization systems.

Chemical Properties and Reaction Mechanism

Antioxidant 2246 functions primarily as a primary phenolic antioxidant and free-radical scavenger.

In oxidation systems:

• The sterically hindered phenolic hydroxyl groups donate hydrogen atoms to neutralize radicals
• Interrupt autoxidation chain reactions
• Reduce thermal-oxidative degradation during processing and long-term service life

Key stabilization features:

• Hindered phenolic antioxidant structure
• Strong heat- and oxygen-aging resistance
• Non-polluting and non-staining behavior
• Effective performance in rubber, plastics, and oil-based systems 

Its stabilization mechanism makes it useful for processing protection, color retention, and oxidative aging control.
