www.perkinelmer.comA Modulus values change with temperature and transitions in materials can be seen as changes in the E’ or tan delta curves. This includes not only the glass transition and the melt, but also other transitions that occur in the glassy or rubbery plateau, shown in Figure 3. These transitions indicate subtler changes in the material.
