Thermal deformation Vicat softening test machine

一. The product introduction:

  The Thermal deformation Vicat softening test machine use a PLC programmable controller for temperature adjustment using a computer display operation. The product is simple in operation, convenient to use, stable in performance, high in product precision, and can monitor the test temperature and deformation amount in time during the test; the system automatically stops heating at the end of the test, and can print the test report and test curve.

   Thermal deformation Vicat softening test machine widely used in the determination of heat distortion temperature (HDT) and Vicat temperature (VST) of thermoplastics, hard rubber and long fiber reinforced composites.

二. Product features of Thermal deformation Vicat softening test machine:

  With sample rack lifting function, the sample holder can be lifted or lowered at the beginning or end of the test. The machine is mainly used for heat distortion temperature and Vicat softening of non-metallic materials such as plastic, rubber, nylon, electrical insulating materials, etc. Determination of point temperature.
