The heat distortion temperature is the temperature at which a piece of PVC, placed in the heat medium with a bending load applied onto it, reaches a specified deflection as temperature rises. The Vicat softening temperature is defined as the temperature where the needle shaped penetrator sinks into the test piece to a specified depth. The Heat Deflection Temperature (HDT), or Heat Distortion Temperature, is a measure of a polymer’s resistance to alteration under a given load at an elevated temperature. It is also known as the ‘deflection temperature under load’ (DTUL) or ‘heat deflection temperature under load (HDTUL)’.

Traditional HDT Vicat test methods use silicon oil as the heating medium, but silicon oil has a high-temperature limit of 300°C. This temperature is not high enough to test new families of materials known as techno-polymers, which have HDT values of up to 500°C. Aluminum oxide is an alternative heating medium for high-temperature applications.The tester is accurate and versatile, with the ability to measure heat distortion temperature (HDT), VICAT softening temperature, and ball pressure. It is also available in models with 3, 4, or 6 testing stations, making it a scalable solution for any laboratory.
