The heat deflection temperature or heat distortion temperature (HDT, HDTUL, or DTUL) is the temperature at which a polymer or plastic sample deforms under a specified load.[1] This property of a given plastic material is applied in many aspects of product design, engineering and manufacture of products using thermoplastic components.
