synergies between antioxidants and light stabilizers

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.

polymer stabilizers

Polymer stabilizers

Light stabilizer are used to inhibit polymer photo-oxidation, which is the combined result of the action of light and oxygen.Like autoxidation this is a free radical process, hence the antioxidants described above are effective inhibiting agents, however additional classes of additives are also beneficial, such as UV absorbers, quenchers of excited states and HALS.
