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 polyphenylene sulfide (PPS) blended with polycarbonate (PC), reinforced glass fiber (GF) and nanometer calcium carbonate (nano-CaCO 3 ) filled PPS ternary composite, as well as the PPS/PC/GF/nano-CaCO 3 hybrid composite, were prepared by means of a twin-screw extruder, and the heat distortion temperature ( T d ) of these materials was measured to .This can be divided into Vicat softening temperature and HDT (heat deflection temperature). In both methods an oil-bath is heated at a defined rate and the temperature is recorded at a deflection or indentation depth specified by the standard. Vicat softening temperature to ISO 306 and ASTM D1525 (VST: Vicat softening temperature) Vicat .
03 HEAT DEFLECTION TEMPERATURE AND VICAT TESTING HEAT DEFLECTION TEMPERATURE AND VICAT SOFTENING TEMPERATURE TESTING: KEY TRENDS AND CHALLENGES The high-performance and specialty polymers market is rapidly expanding. Much of this growth comes from the automotive industry, which is experiencing a major shift. Fuel . 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)’.Ray-Ran 3 & 6 Station Heat Distortion & Vicat Softening Point Apparatus.
