Heat Deflection Temperature vs. Dynamic Mechanical Analysis (Part 3)
DMA provides a rich and detailed picture of polymer performance, and it can be challenging to understand all the things that we can and should know about our materials. But the fact that it may be hard does not mean that it should not be attempted.

Part 1: Heat Deflection Temperature vs. Dynamic Mechanical Analysis
Does the industry need a better way of reporting the temperature-dependent behavior of plastics? With DMA, it already has one. But it’s been glacially slow to catch on.
