Reading a TMA Curve — Why Do We Measure TMA?
💡 In This Article What physical-property data TMA provides for epoxy development The physical relationship between CTE mismatch, warpage, and delamination in bonded dissimilar materials How the crosslinked structure of epoxy differs from thermoplastics and affects TMA behavior, including α₁ and α₂ How TMA can be used to simulate production-like thermal conditions In the previous … Continue reading Reading a TMA Curve — Why Do We Measure TMA?
How Do You Read a DSC Curve? — Why Is DSC Used to Determine Tg?
💡 In This Article DSC analysis: How Tg can be identified from changes in heat capacity How to read Tg from a DSC curve: Why Tg is usually identified from a baseline shift rather than simply looking for a peak Why comparing DSC curves can be more informative than comparing Tg values alone Using DSC … Continue reading How Do You Read a DSC Curve? — Why Is DSC Used to Determine Tg?
Why Are There Different Analytical Techniques for Measuring Tg?
💡 In This Article Tg is not simply a single number — it reflects a complex set of property changes associated with polymer segmental motion Why Tg values differ between analytical techniques — how DSC, DMA, TMA, and other methods observe different physical manifestations of the same glass transition When developing an adhesive, two properties … Continue reading Why Are There Different Analytical Techniques for Measuring Tg?
