Reading a DMA Curve ② — What Does Storage Modulus Really Tell Us?

💡 In This Article What Storage Modulus really represents Why the onset of the rapid Storage Modulus drop can be more important than the Tan δ peak Why absolute Storage Modulus retention at the actual operating temperature can matter more than a single Tg value How formulation changes can alter the Storage Modulus curve In … Continue reading Reading a DMA Curve ② — What Does Storage Modulus Really Tell Us? →

Reading a DMA Curve ① — Why Do Researchers Rely So Heavily on DMA?

💡 In This Article How the measurement purpose of DMA differs from DSC and TMA Why Tg values differ between techniques and how this relates to segmental motion How the position, height, width, and shape of the Tan δ peak can provide clues about polymer structure and relaxation behavior How DMA can be used to … Continue reading Reading a DMA Curve ① — Why Do Researchers Rely So Heavily on DMA? →
