OIT Tester for Polyolefin Resin Thermal Stability

Isothermal oxidation induction time instrument for checking antioxidant effectiveness in polyolefin compounds. Used by resin producers, pipe and cable compounders to judge processing and long-term thermal stability of batches.

Specification

Samples are held at constant high temperature in an oxygen stream until oxidation begins. The time to onset is recorded as oxidation induction time. The result predicts long term stability during processing and service.

Features

• Isothermal operation to 300 deg C
• Gas switching oxygen and nitrogen
• Digital timer and sensor
• Sample pans in aluminium
• Program storage for runs
