Xrw-300 Hdt/vicat Tester

Usage :
This tester is mainly used to do the HDT test and VICAT test for non-metal materials: such as plastic rubber and nylon.

Introduction :
Vicat softening point is the temperature at which a standard indenter penetrates 1mm into the surface of a plastic test specimen under a constant load when the temperature is raised at a uniform rate.

HDT is the temperature when a standard test specimen is subjected to a bending stress to produce one of the nominal surface stresses given in the relevant part of the international Standard. The temperature is raised at a uniform rate and the temperature at which a specified deflection occurs is measured.

The attained heat resistance rate of plastic materials is a widely required parameter for product characterization for quality control as well as for evaluating their conformity to the previewed applications.
