Hindered Phenol Antioxidant HPAO
Oxidation of polymers can lead to many undesirable effects including color changes, formation of rough surface morphology, changes in melt viscosity and reduction in mechanical properties, which can affect the service life of the polymer or the final product. Oxidation can occur at every stage of the polymer life cycle, during the production and storage of polymer resins, during high temperature melt processing operations, during the processing of resins into articles, and during the use of the articles. In addition, exposure to UV rays from sunlight also accelerates the oxidation process. Adding synthetic phenolic antioxidants for polymers can inhibit and ...

Hindered Amine Light Stabilizer
Hindered amine light stabilizers (HALS) are important stabilizers for long-term thermal protection of polymers, and are very effective in inhibiting polymer degradation caused by free radicals at medium and low temperatures. Hindered Amine Light Stabilizers (HALS) exhibit excellent UV protection by scavenging free radicals generated by photodegradation to prevent polymer degradation. After the HALS chemical scavenges free radicals, it returns to its original structure and repeatedly scavenges free radicals for effective long-term performance. hals light stabilizer can be classified according to their molecular weight (MW): HALS UV stabilizer with a low molecular weight of approximately 200 to 500 g/mole are generally ...
