Analysing the thermal properties and transitions to help you understand polymer performance
Thermal analysis testing of polymers is important for understanding the changes in polymer properties as a function of temperature, and to also determine the thermal transition points which can assist in material selection for an application, assist in understanding polymer performance in service, or assist in polymer failure investigations.
ExcelPlas offers a number of thermal analysis techniques to measure these properties:
Differential Scanning Calorimetry (DSC analysis of polymers) is an important tool which determines parameters such as polymer glass transition temperatures, melting temperature, crystallization temperature, enthalpy, degree of crystallinity, extent of curing, onset of oxidation (by time and temperature) and thermal history effects.
Thermal Gravimetric Analysis (TGA analysis of polymers) is another important technique that provides a measurement of mass loss as a function of temperature, and can determine parameters such as onset decomposition temperature, peak decomposition temperature, breakdown proportion of oils, polymer, carbon black, ash residue components.
Thermal Mechanical Analysis (TMA analysis of polymers) is an analysis technique which measures the dimensional changes of a sample as a function of time/temperature/force, crucial for determining the coefficient of linear thermal expansion (CTE) and glass transition temperatures.
