Identification and Quantitation of Antioxidant Packages in Polymer Materials

Antioxidant components are added to polymers to absorb oxidation, and shield the polymer material from degradation. Degradation can include weathering, brittleness, and yellowing. These antioxidant packages can vary depending on the manufacturer, molder, application or identity of the polymer material. Common antioxidants include:

  • Irganox 1010
  • Irganox 1076

  • Irgafos 168

  • Butylated hydroxytoluene (BHT)

  • Vitamin E

Impact Analytical has 40+ years of experience characterizing polymer materials, including antioxidants. We have methods developed for specific polymer materials, including polyolefins (polypropylene, polyethylene), PVC, Polyesters, Polyamines, Polyols, Polyurethanes and others. These methods efficiently extract the polymer additives from the material, allowing for accurate identification and quantitation.
