Glass Transition Temperature in Plastics
👉 Glass Transition is a temperature at which an amorphous polymer moves from a hard or glassy state to a softer, rubbery or viscous state.
👉 Glass transition temperature is an important property when considering polymers for a particular end use or application.
👉 The value of glass transition temperature depends on the strain rate and cooling or heating rate.
👉 At glass transition temperature, carbon chains start to move.
