Testing principle of hot deformation Vicat softening point temperature tester:

Hot deformation temperature (HDT): The temperature at which the specimen uniformly heats up under a constant three-point bending load and reaches the specified bending strain is measured.

Vicat softening point (VST): The temperature at which a standard indenter is pressed into a sample 1mm deep under a fixed load, reflecting the thermal stability of the material.

Hot deformation Vicat softening point temperature testerIntroduction: It is a key equipment used to test the heat distortion temperature (HDT) and Vicat softening point temperature (VST) of non-metallic materials such as plastics, rubber, nylon, etc. It is widely used in quality inspection institutions, enterprise laboratories, and scientific research fields.
