    Antioxidants CROW

    Antioxidants. Polymers will change over time when exposed to radiation, excessive heat and/or corrosive enviroments. These changes are the result of oxidative degradation caused by free radicals which form through hydrogen abstration or homolytic scission of carbon-carbon bonds when polymers are exposed to heat, oxygen, ozone, or light.

  • polymer stabilizers

    Polymer stabilizers

    Primary antioxidants (also known as chain-breaking antioxidants) act as radical scavengers and remove peroxy radicals (ROO•), as well as to a lesser extent alkoxy radicals (RO•), hydroxyl radicals (HO•) and alkyl radials (R•). Oxidation begins with the formation of alkyl radials, which are formed when the high temperatures and high shear stress experienced during processing snaps the
