Design Properties for Polymer Engineering: Dynamic Mechanical Analysis (DMA) of Unfilled Engineering Polymers

Hello and welcome to a new post. Today I present to you dynamic mechanical analysis (DMA) data of most used unfilled engineering polymers. 

In a previous post we discussed the storage modulus vs. temperature behavior of different high performance amorphous and semicrystalline polymers. Also how DMA can be used as a polymer material selection tool. Here you can find the collection of all my posts on design properties for plastics engineering - engineering and high performance polymers.

In general, the DMA is a thermo-analytical method that estimates the viscoelastic properties of a given material over the course of different temperatures. It steps away from a single point view toward a multipoint data view which is beneficial for polymer material selection tasks.

Figure 1 shows the elastic modulus of ABS, POM, PBT, and PA 6.6 and Figure 2 shows it for PMMA, POK, PC, and mPPE. Figure 3 contains all polymers in a single chart.

Figure 3: Elastic Modulus of ABS, POM, PBT, PA 6.6, PMMA, POK, PC, and mPPE.
