The investigation of the melting behavior of plastics is crucial to gain insights into their thermal properties and processability. Various methods can be used to investigate the melting behavior of plastics.
Differential Scanning Calorimetry
(DSC)
This method measures the change in heat flow of a plastic as it is heated or cooled. DSC can provide information about the melting point, melting temperature, melting enthalpy, and glass transition of a plastic.
Thermo-Mechanical Analysis (TMA)
TMA is used to investigate the mechanical properties of a plastic as a function of temperature changes.
It can provide information about the thermal expansion coefficient and glass transition temperature of the plastic.
Rheology
Rheological investigations include measuring the viscosity and flow behavior of plastics at different temperatures. This can provide information about the melting behavior and flow behavior of the plastic.
Thermogravimetric analysis (TGA)
TGA is used to investigate the weight loss behavior of a plastic when heated. This can provide information about the degradation behavior and thermal decomposition process of the plastic. It is important to note that the choice of test method depends on various factors, such as the specific plastic material and the information required.
