Glass transition temperature is the temperature at which an amorphous polymer changes from a hard/glassy state to a … Webloss tangent peak fall within the sound frequencies at the relevant temperature. Rubber blends, polyurethanes, and polyureas are often used in these applications because their broad transitions make the acoustic response less sensitive to temperature. 8,9. Nature also uses the glass transition phenomenon to dissipate energy. Under physiological
