HDT/ Vicat Tester, also named HDT/VICAT Heat Deflection Testers which is mainly used to do the HDT test and Vicat test for non-metal materials: such as plastic, rubber, nylon and electrical insulating material. They are the perfect test tools for chemical industry, R&D department and academies or colleges.

HDT/ Vicat Tester DW5340J

HDT/VICAT Tester is used to determine heat distortion temperature and Vicat softening temperature of high polymer materials, as an index of controlling quality and identifying thermal property of new products.

Sample is immerged in liquid and fixed by a pressure needle. Heat liquid with specified heating rate, sample becomes soft and will distort under the pressure. The liquid temperature is Vicat softening temperature when distortion reaches 1mm

Follows are features of HDT/ Vicat softening temperature Tester

  • Deformation acquired via dial indicator, heating speed set by temperature controller;
  • Sample holder automatically up and down, possible to test 3pcs of samples at a time;
  • Nice appearance, novel design, high reliability and precision, easy to operate;
  • Real-time curve, and the data can be processed on the computer

Application

Application of HDT/ Vicat Tester

“HDT” test means the test determines the temperature at which a specified deflection occurs when a standard test specimen is subjected to a bending stress, to produce one of the nominal surface stresses according to international standards.

This test is important for both quality control and research into plastics.

“VICAT” test means the test determines the temperature at which a standard indenter penetrates 1mm into the surface of a test specimen under load.

It is used to establish the difference between many types of thermoplastic materials with regard to their softening properties.

Working condition is as belows : Environment temperature: 10℃~40℃

Relative humidity: 30%~80%, Without shock and corrosive medium in working environment, Fix the tester on firm base without vibration

Working without strong electromagnetic interfere, strong air blow or convection, Water source should be provided, With exhaust equipment in working environment
