Glass Transition Temperature
Glass transition temperature (Tg) is the temperature at which a material changes from a hard, brittle state to a softer, more flexible state, resembling a super-cooled liquid. It primarily applies to polymers and certain other amorphous materials. Below Tg, the material is rigid and glass-like, but as the temperature rises to Tg and beyond, it becomes more rubbery and can flow more easily. Understanding Tg is important in manufacturing processes and in determining how a material behaves under different temperature conditions, affecting its durability and performance in applications like packaging, coatings, and electronics.

Glass Transition Temperature (Tg) is the temperature at which a material transitions from a hard, glassy state to a more flexible, rubbery state. Below Tg, substances like plastics behave rigidly and are less likely to deform under stress. As the temperature rises past Tg, the material becomes more pliable, allowing it to stretch or bend. This property is crucial in materials science, as it influences how materials expand, contract, and perform under different temperatures, affecting their applications in products like packaging, electronics, and everyday objects. Understanding Tg helps in selecting the right materials for specific environments.
