Thermoplastic materials are widely used in many industries because of their unique properties, low weight, attractive price, and recycling possibilities. The four main techniques of thermal analysis, DSC, TGA, TMA, and DMA are ideal for characterizing such materials. The most important advantage is that properties can be measured as function of temperature or time over a wide temperature range, from –150 to 1600 °C.

In this Webinar, we will show how thermal analysis is used to analyze thermoplastic materials and will present some typical examples of samples measured by DSC, TGA, TMA, or DMA.

The Webinar covers the following topics:

  • Introduction
  • Basic properties of thermoplastics
  • Typical questions
  • Thermal analysis
  • Industries and applications
  • Instrumentation and applications
    - Differential Scanning Calorimetry (DSC)
    - Thermogravimetry (TGA)
    - Thermomechanical Analysis (TMA)
    - Dynamic Mechanical Analysis (DMA)
  • Summary

Thermal analysis is an excellent method for identifying and characterizing thermoplastics because their properties are strongly dependent on temperature.

Thermoplastics
Thermoplastics soften on heating and can be molded into thousands of different shapes using methods such as injection molding or extrusion. Providing decomposition does not occur, the cycle of heating, molding, and cooling can be repeated very many times. This behavior distinguishes thermoplastics from elastomers or thermosets, which have are molded by means of an irreversible chemical reaction.

Among the most widely used thermoplastics are polyethylene, (PE), polypropylene, (PP), and polyesters such as polyethylene terephthalate, (PET).

Techniques covered in the webinar
Different thermal analysis techniques that can be used to characterize thermoplastics. The most frequently used methods are DSC, TGA, TMA, and DMA.

The most important effects that can be analyzed by DSC are the glass transition, melting behavior, reaction enthalpies, and the influence of fillers.

For TGA, the main applications are content analysis, thermal stability and evaporation behavior.

TMA is normally used to study the expansion or shrinkage of materials.

DMA is the best method for characterizing viscoelastic behavior of materials.
