Definitions

  • Glass Transition Temperature (Tg) — 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.
  • Continuous Use Temperature — Function of the thermal breakdown of the polymer. Difficult to increase by adjusting additives.
  • Heat Deflection Temperature — Temperature at which a material will deflect a specified amount at a specified load. Good indicator of short term/low load thermal capabilities.
