How to Optimize OIT Tests?

OIT is the abbreviation for oxidative induction time. It provides information about the oxidative stability of mainly polymer materials. This information is important because plastic parts age throughout their lifetime due to exposure to environmental elements such as heat, oxygen, light and radiation. Aging causes the degradation of the physical properties of the polymers and will lead to their failure. Antioxidants are often added during the plastics formulation to hinder the aging caused by oxygen and to increase their lifetime. Because the reaction between polymers and oxygen (O2) is exothermic, OIT determination using Differential Scanning Calorimetry (DSC) is an ideal solution to study this process.
