Impact transition temperature
Witryna21 sty 2024 · The value of glass transition temperature depends on the mobility of the polymer chain, and most synthetic polymer ranges between 170,000 to 500,000. The transition from glass to the rubber-like state is an integral feature of the polymer attribute, signifying a region of drastic changes in the physical properties such as … Witryna12 wrz 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.
