Thermal Analysis Techniques for Polymers, Part 1: DTA, TMA, and DMA


In this blog post, we are going to start a discussion about the most common thermal analysis techniques used to investigate the properties of polymers.  In part 1 of this series, our focus will be on:

  • differential thermal analysis
  • thermomechanical analysis; and
  • dynamic mechanical analysis 

This discussion will include how these tests are performed and what kind of properties can be determined from the resulting data.
