Antioxidants
The two main classes of antioxidants are free-radical scavengers and peroxide scavengers. The free-radical scavengers are sometimes called primary antioxidants or radical chain terminators whereas peroxide scavengers are often called secondary antioxidants or hydroperoxide decomposers.

Use of Antioxidant Masterbatch for Polymer Stabilization
Secondary – used as a process stabilizer. This type of stabilization is an effective way to protect the polymer during processing, especially when the polymer undergoes multiple heat histories. Typical chemistries employed include phosphites or thioesters. Primary/Secondary Combination – Both primary and secondary antioxidants are often used in combination. In this way, the polymer is protected both during the processing step and throughout its service life.
