Differential Scanning Calorimetry (DSC): determination of Oxidation Induction Time (OIT)
The Oxidation Induction Time is the time for which an antioxidant stabilizer system present in a material inhibits oxidation while the material is held isothermally at a specified temperature in a stream of oxygen.
Practically a sample is placed in a Differential Scanning Calorimeter (DSC) and heated to a specified temperature under N2 after which the atmosphere is changed to O2 and the temperature is kept constant (i.e. isothermal). A strong increase in exothermic heat flow indicates the time of depletion of antioxidant stabilizers and the onset of oxidation reactions.
Make sure to include information on the aim of your measurement, your desired measurement conditions (temperature, atmosphere,...) and the chemical nature (e.g. PP, PE, PET, PA,... preferably with a safety datasheet) of your polymer with your order. Extra costs may apply depending on the complexity and duration of your requested conditions.
