Parameters of Rubber Oxidative Induction Time(OIT) Tester 

Oxidative Induction Time Tester is used to measure the oxidative induction time (OIT) of plastic or rubber materials. The time is used as an indication of the oxidative thermal stability of plastic or rubber materials. When samples are placed into the rack of the instrument and protected in Nitrogen, heat them at the rate of 20°C/min until the temperature reaches 200°C±0.1°C; Hold the temperature for 7 minutes and then quickly switch Nitrogen to Oxygen. Samples will react with Oxygen to produce heat energy. Curve of change in temperature will be recorded and the time when there is an obvious change on the curve is regarded as the oxidative induction time.
