AbolishedDetermination of glass transitiontemperature of plastics--Thermomechanical analysis
塑料玻璃化温度测定方法 热机械分析法
Application Summary AI generated
This standard specifies the thermomechanical analysis (TMA) method for determining the glass transition temperature of plastics. It is applied in material testing and quality control within the rubber and plastics industry to characterize the temperature at which amorphous or semi-crystalline polymers transition from a hard, brittle state to a softer, rubbery state. The method is used for product development, formulation comparison, and ensuring thermal performance specifications for plastic components.
