How To Measure The Pet (Polyester) Glass Transition Temperature?

In order to study the quality and characteristics of materials, many industries use differential scanning calorimeter （DSC） to test the glass transition temperature of materials, especially the glass transition temperature of PET (polyester), which is also a relatively common measurement. Differential Scanning Calorimeter  What is glass transition temperature? Glass transition temperature (Tg) refers to the temperature corresponding to the transition from glassy state to high elastic state. Glass transition is an inherent property of amorphous polymer materials and a macroscopic manifestation of [...]

What is Oxidation Induction Time Analyzer?

Oxidation induction time analyzer is a common thermal analysis instrument used to measure the thermal stability and oxidation stability of materials. The OIT test method can evaluate the thermal degradation process of a sample by measuring its oxidation induction time at high temperature, thereby obtaining important information about the stability and durability of the material.   OIT testing typically use differential scanning calorimetry (DSC), a technique that measures the thermal degradation temperature and reaction rate of a sample at elevated temperatures under a predetermined [...]

Principle and structure of Differential Scanning Calorimeter(DSC)

Differential Scanning Calorimeter is a thermal analysis instrument that tests the thermal effect of substances in the process of heating or cooling. It can study the relationship between the physical and chemical change rate of substances and temperature, as well as the performance of certain physical and chemical properties of substances under the action of thermal energy. feature. Under the program control temperature, the temperature difference between the substance and the reference substance can also be measured as a [...]

What Can a Differential Scanning Calorimeter（DSC) Measure?

Differential scanning calorimeter is also referred to as DSC. DSC is to make the sample under the control of a certain temperature program (rise/decrease/constant temperature), and observe the change process of the heat flow power difference between the sample end and the reference end with temperature or time. Obtain relevant thermal effect information such as the endothermic, exothermic and specific heat changes of the sample during the temperature program, and calculate the endothermic and exothermic heat (enthalpy) and characteristic [...]

The Difference Between a Differential Scanning Calorimeter DSC And a Differential Thermal Analyzer DTA

Differential Thermal Analysis (DTA) is an important thermal analysis method, which refers to a testing technique that measures the relationship between the temperature difference between a substance and a reference substance and the temperature or time under program temperature control. This method is widely used to determine the characteristic temperature of a substance and the amount of heat absorbed or released during thermal reactions, including physical or chemical reactions such as phase change, decomposition, compounding, solidification, dehydration, and evaporation [...]

Application and Experienceof Differential Scanning Calorimetry DSC In Polymer Material Research

1 The working principle of differential scanning calorimetry (DSC)Differential Scanning Calorimetry (DSC) is a thermal analysis method developed after the 1860s. It is a method of measuring the relationship between the power difference input to the sample and the reference material and the temperature under the control of the program temperature. Kind of technology [1,2]. The accuracy of this change in measurement difference is higher than the measurement of the absolute value of heat flow or power [3]. Its [...]
