Plastics. Determination of dynamic mechanical properties - Glass transition temperatureWhat is ISO 6721 11 Glass transition temperature of plastic about? The glass transition temperature (Tg) is an indicator of the transition from a hard and relatively brittle glassy state to a rubbery or viscous liquid state in an amorphous polymer or in amorphous regions of a partially crystalline polymer. Measured Tg values using instrumentation can vary because of material characteristics and or the test set up. ISO 6721 is a series of plastics
