Code: 10240. Antioxidants for plastic materials are protective additives for both products made with virgin and recycled polymers.

Antioxidants in plastics work by inhibiting the oxidation process. This chemical principle involves the ability of antioxidants to capture and neutralize free radicals, which are highly reactive molecules responsible for the oxidation of plastic materials.

The presence of antioxidants helps prevent the breakage of polymer chains and the loss of material properties, thus helping to maintain the integrity of plastics over time.

Our antioxidants for plastic materials can be of two types:

- Phenolic antioxidants

- Phossite antioxidants

Phenolic antioxidants interfere with chain propagation by disrupting the free radical. Phenolic antioxidants act as H donors, offering the peroxy radical an easily extractable hydrogen, avoiding the extraction of hydrogen from the polymer structure.

Phosite antioxidants transform hydroperoxides into non-radical, non-reactive and thermally stable products. Secondary antioxidants protect primary antioxidants during processing.
