Definitions

Temperature at which a material goes from a glassy state to a rubbery state. Key property changes include softening, reduction in density, and large drop in strength and modulus.

Function of the thermal breakdown of the polymer. Difficult to increase by adjusting additives.

Temperature at which a material will deflect a specified amount at a specified load. Good indicator of short term/low load thermal capabilities.
