HDT and Vicat temperatures are critical properties for measuring the quality and performance of high-performance polymers: The HDT test for plastics measures the temperature where deformation occurs under a .This test method is used to assess the dimensional stability of plastics as a function of temperature and determine the Vicat softening temperature. The Vicat softening temperature (VST) is the temperature at which a standard . This depends on application. Definitions: Vicat softening point.Vicat softening temperature or Vicat hardness is the determination of the softening point for materials that have no definite melting point, such as plastics. It is taken as the temperature at which the specimen is penetrated to a depth of 1 mm by a flat-ended needle with a 1 mm² circular or square cross .the Vicat softening temperatures. The heat distortion temperature shows another behaviour. Here both, the HDT A and the HDT B values increase with increasing filler content (Fig. 3.6 a, b). Vicat softening temperature und heat distortion temperature - application 1 Landolt-Bo¨rnstein New Series VIII/6A3 DOI: 10.1007/978-3-642-55166-6_14
Heat Deflection and Vicat Softening Temperature tests are essential for evaluating the thermal behavior of plastics under heat and stress. The HDT Vicat Testers, used for determining both the Heat Deflection Temperature (HDT) and Vicat Softening Temperature, help manufacturers ensure their materials meet stringent thermal performance requirements.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 .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)’.

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 .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.It is mainly used for the determination of heat distortion temperature and Vicat softening point temperature of non-metallic materials such as plastic, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high strength thermosetting laminates. It is easy to operate and precise in control.Discover the 3 & 6 Station Heat Distortion & Vicat Softening Point Apparatus, providing the highest quality of testing equipment. .

The test specimen is loaded in three-point bending in the edgewise direction. Heat distortion temperature This material test assesses the dimensional stability of plastics as a function of temperature. It determines the temperature at which a specified deflection occurs .Thermoplastic polyurethanes rely on heat as they acquire new forms during extrusion and injection molding processes. As versatile TPUs are heated and reheated, and sometimes combined with other materials to create high-performance composites with their own unique characteristics, a detailed assessment of the thermal properties of individual TPU grades is .
the standard test specimen and the temperature is raised at a uniform rate. Note: When ISO 75 is used the result is referred to as the Heat Distortion Temperature or Heat Deflection Temperature (HDT). Real Life Performance Any test is only an approximation of the real life behavior. Tests are naturally accelerated to The test specification for the Vicat softening temperature testing is ASTM D1525 and ISO 306. Compared with the Heat Deflection Temperature (HDT), Vicat softening temperature test measures the temperature at which the specimen loses its stiffness and softens. HDT test measures the temperature at which the specimen loses its load bearing .
