Because of their molecular structure, polymeric materials have different properties compared to other materials, like metals. Due to their viscoelastic nature, polymeric material properties our temperature dependent. As the temperature is increased, the polymer chains are further apart, there is more free volume and kinetic energy, and the molecules can slide past one another and disentangle more easily. The physical properties and performance of polymeric materials, such as strength, stiffness, and impact resistance, are highly dependent on the temperature at which the stresses applied. Over a temperature range, polymers will pass through key transitions, such as beta transitions and glass transitions, as well as softening and melting. Understanding the implications of these transitions and their correlation to molecular structure is useful in material selection and avoiding premature failure.
