This databook describes practical uses for DMA, covering 120 families of thermoplastics. All tests were conducted exclusively for this publication, and the data are not available through any other source. The book explains the correlation between time and temperature-dependence and illustrates the ways in which time-dependent responses such as creep and stress relaxation affect the practical utility of different materials. Basic polymer structures are discussed, and test results show how these structural details can be detected and understood.

From the Foreword: “...All plastic materials have been tested using the same methods and therefore comparison of the results is very meaningful. In addition to providing performance data on a broad spectrum of plastics, [this book] provides an excellent discussion of how to use DMA data and what it means, practically speaking, to the plastics engineer. After reading this manuscript, the versatility and necessity of using DMA data as a powerful engineering tool becomes apparent and clear...”

Target Audience: Polymer and plastics engineers, designers, technologists, and researchers; also upper-level students interested in plastics engineering and analysis.
