After processing step, plastic products usually contact oxidation source (ex. Oxygen in atmosphere), so their structures are broken by oxidation processes. Preventing the oxidation processes of Antioxidant helps to increase life time of products.

Antioxidant is used bring some advantages, such as:

  • Making plastic structure is more stable, so plastics keep their properties.
  • Preventing the discoloration during processing and using time.
  • increasing the life time of final products

Antioxidant has to use for some cases:
