Synergies between Antioxidants and Light Stabilizers
Antioxidant and processing stabilizers are necessary to prevent this degradation, maintaining the properties of the polymer material. Besides protecting the polymer design, using adequate processing stabilizers positively influences the stability of the plastic against the detrimental action of UV radiation.

BASF Antioxidant - Polymer Additives
Phosphites are most effective during processing and protect both the polymer and the primary antioxidant. Hydrolytically stable phosphites are the most frequently used processing stabilizers in high-performance additive systems. Thioethers are useful only in increasing the long-term thermal stability in conjunction with phenolic antioxidants. The use of thioethers is limited to areas where their possible effect on odor or taste and their negative interaction with HALS is not important.

Polymer stabilizers
Stabilizers are a class of chemical additives commonly added to polymeric materials, such as plastics, to inhibit or retard their degradation. Polymers can be subject to various degradation processes, including oxidation, UV-damage, thermal degradation, ozonolysis, combinations thereof such as photo-oxidation, as well as reactions with catalyst residues or other impurities. These processes all degrade the polymer on a chemical level, leading to chain scission that can adversely affect its mechan
