Antioxidant Supplier, Protect Polymer From Thermal
Antioxidant – protect polymer from thermal-oxidation degradation. Antioxidant additives can be classified into hindered phenolic, metal deactivates, amine, phosphites, thioesters and binary blends. Hindered phenols are used as primary antioxidants. Organo-phosphites are sometimes used as secondary antioxidants.

ANTIOXIDANTS. Antioxidants protect plastics and other materials against thermally induced oxidation. This process can lead to a number of undesirable effects, including discoloration, changes in melt viscosity, and deterioration of mechanical properties. As a result, the useful life of the polymer or final article is limited.

In conclusion, a certain minimum amount of antioxidant is necessary in PE to stabilize and protect the polymer from autoxidative degradation. Primary antioxidants and thioesters are added to the polymer to provide end use product stability while phosphites or phosphonites are added to provide color and processing stability during pelletization and extrusion/molding.

Send InquiryMechanism of antioxidant interaction on polymer oxidation
The mechanism of polymer oxidation by radiation and thermal ageing was investigated for the life evaluation of cables installed in radiation environments. The antioxidant as a stabilizer was very effective for thermal oxidation with a small content in polymers, but was not effective for radiation oxidation.
