Antioxidant 168
What is Antioxidant 168?
Antioxidant 168 is a hydrolytically stable phosphite-based processing stabilizer. It effectively reacts with hydroperoxides generated during the autoxidation of polymers in processing, preventing thermal degradation and enhancing the efficiency of primary antioxidants for improved long-term stability.

The Role of Antioxidant in Plastic
Antioxidants play a critical role in maintaining the stability, durability, and performance of plastic materials throughout their lifecycle. Without antioxidant protection, plastics are prone to degradation during processing and long-term use, which can result in discoloration, brittleness, loss of mechanical strength, and reduced lifespan.
Key Functions of Antioxidants in Plastics:
Thermal Stabilization:
During high-temperature processing like extrusion or molding, plastics are exposed to oxygen which can cause oxidative degradation. Antioxidants help neutralize free radicals and prevent this damage.
Long-Term Aging Resistance:
In end-use environments, especially under heat, light, or oxygen exposure, antioxidants maintain the polymer’s integrity and appearance over time.
Preservation of Properties:
Helps in retaining color, elasticity, tensile strength, and other key physical properties of plastic materials.

Polymer Antioxidant
Polymer antioxidants can be added to improve the shelf life of the product or to improve its high-temperature stability. while adding a stability margin during thermal processing.
Antioxidant additives can be classified into hindered phenolic, metal deactivates, amine, phosphites, thioesters and binary blends.
Hindered phenols are used as primary antioxidants. phosphites are sometimes used as secondary antioxidants. There is a synergistic effect when using different antioxidants blended together and the combination can meet heat and processing stability requirements.
