Thioester Antioxidant

Introduction to Thioester Antioxidants

Similar to phosphorus antioxidants, thioester antioxidants are active hydroperoxide decomposers, so they are used in large quantity as secondary AOs, especially for rubber-like polymers, or black color wire and cables.

They do not react with radicals and thus will only improve the polymers’ color stability

rather than the melt flow index.

One disadvantage of thioester antioxidants is its unpleasant odor, which might cause smell issues in end applications.
