Polymer Storage Modulus vs. Temperature: Thermal Transition Analysis #1444056 (License: Personal Use)

This log-scale graph displays the storage modulus (E′) of two polymer samples as a function of temperature from -60°C to 100°C. The red curve (open circles/squares) represents a formulation with higher modulus retention above the glass transition, while the black curve (filled circles/squares) shows a sharper drop, indicating a lower Tg near 25°C (marked by dashed line). Both exhibit typical viscoelastic behavior with distinct rubbery plateau regions.

Used in materials science and polymer engineering webpages or technical reports to illustrate dynamic mechanical analysis (DMA) results; supports user intent to compare polymer thermal performance, identify Tg, or select materials for specific operating temperatures.
