An elastomer with a glass transition temperature (Tg) of 25° C will lose its elasticity below 25° C.

Question

Quizplus · Accepted Answer

The glass transition temperature (Tg) is the temperature at which a material transitions from a rubbery, elastic state to a more brittle, glass-like state. If the temperature drops below the Tg, the material will start to behave more like a solid than a rubbery material, and may lose its elasticity. Therefore, an elastomer with a Tg of 25°C will indeed lose its elasticity below 25°C.
