Plastic Differential Thermal Analyzer

Plastic Differential Thermal AnalyzerUsually refers to differential scanning calorimetry (DSC) used for thermal performance analysis of plastic materials. DSC is a thermal analysis technique that studies the thermal properties and physicochemical changes of materials by measuring the amount of heat absorbed or released by a sample during heating or cooling.

The core principle is to measure the heat flux difference between the sample and the reference material at a temperature controlled by the program. When plastic samples undergo phase transitions (such as melting, crystallization) or chemical reactions during heating or cooling, they absorb or release heat. The instrument records these heat changes and generates a DSC curve

Application scope:

Oxidation Induction Time (OIT) is a measure of the time it takes for a sample to undergo an automatic catalytic oxidation reaction under high temperature (200 degrees Celsius) oxygen conditions. It is an indicator for evaluating the material's ability to resist thermal degradation during molding, storage, welding, and use.

The oxidation induction period (OIT) method is a method that uses differential thermal analysis (DTA) to test the degree of accelerated aging of plastics in high-temperature oxygen based on the exothermic reaction of plastic molecular chain breakage.

The principle is to place the plastic sample and an inert reference material (such as alumina) in a differential thermal analyzer, and rapidly replace the inert gas (such as nitrogen) in the sample chamber with oxygen at a certain temperature. Test the changes in DTA curve (differential thermal spectrum) caused by sample oxidation and obtain the oxidation induction period (time) OIT (min) to evaluate the thermal aging resistance of plastics.
