The glass transition temperature of a polymer is the … WebSep 12, 2024 · At the glass transition temperature, the physical nature of the material changes subtly. It goes from being a rubbery, flexible material at higher temperature, above the glass transition, to a glassy, harder material at a lower temperature. The material is still a solid either way, but there is a definite change in how it responds to stimuli.
WebMelting Point (MP) and Glass Transition Temperature (Tg) are the most important thermodynamic parameters for the common polymers. These properties can be easily and quicky determined by DSC. Melting point temperature range (0 C) Glass transition temperature range (0 C) Polyethylene (High Density) ABS Tg: to 1250C CHCH2 CH = … WebWith rising temperature, the torsion modulus curve falls and damping behavior increases. This is the so-called glass transition zone, where damping reaches a maximum. After the glass transition zone, the torsion modulus curve flattens. This condition is described …
