Metal Deactivators

Metal Deactivators

Special Phenolic Antioxidants

Metal deactivators are special phenolic antioxidants containing functional groups that enable them to complex with and deactivate metal ions, which can accelerate the oxidation of plastics. They are widely used in wire and cable insulation applications to protect plastics from exposure to metals such as copper during end use.
