HDT / VICAT Heat Deflection Test Systems

Plastic materials are very sensitive to temperature changes. Unlike metals, polymers are extremely sensitive to changes in temperature and many factors contribute to affect their thermal behavior, which is a rather complex property. The thermal properties of plastic materials are equally as important as the mechanical properties. Selecting a suitable plastic is a big challenge for Designers and material selectors of plastic products for elevated temperature performance.

In other words, they need to have a deep understanding of the short-term effect of temperature on the material selected. HV-3000-D3/D6 are designed to determine the behavior of plastic materials as a function of the temperature (short-term effect).

HV-3000

HV-3000-D, the latest compact model of DT/VICAT tester, is designed to measure both heat deflection temperature (HDT) and VICAT softening temperature (VST) for evaluating the thermal property of plastic materials.

The lightweight design makes HV-3000-D an ideal choice of compact HDT-VICAT tester. The information of temperature in real time from each test station can be read in a single display screen allowing user to monitor test more conveniently. The design of the tester complies with international standards including ASTM, ISO and DIN.

VICAT Softening temperature

"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-section. For the VICAT A test, a load of 10 N is used. For the VICAT B test, the load is 50 N.

Standards to determine VICAT softening point include ASTM D 1525 and ISO 306, which are largely equivalent.

Heat deflection temperature
HDT / VICAT Heat Deflection Test Systems

The heat deflection temperature or heat distortion temperature (HDT, HDTUL, or DTUL) is the temperature at which a polymer or plastic sample deforms under a specified load. This property of a given plastic material is applied in many aspects of product design, engineering, and manufacture of products using thermoplastic components.

Applicable Standards

HDT Test: ISO 306, ASTM D1525, DIN 53460 and equivalents

VICAT Test: ISO 75, ASTM D648, DIN 53461 and equivalents

HDT Series- Heat Deflection Tester

HDT / VICAT Heat Deflection Test Systems

Heat Deflection Temperature Tester (HDT1) is a single station and low-cost system designed in accordance to ASTM D648 as well as ISO 75 to measure material's ability to perform for a short time at elevated temperatures while supporting a load. The test measures the effect of temperature on stiffness: a standard test specimen is given a defined surface stress and the temperature is raised at a uniform rate.

Specification:
  • Temperature: Ambient Room~300°C
  • Heating system: 2°C per minute, difference 1°C
  • Loading Weight: 200N without any weight. Accessories: 0.1Nx1, 0.2Nx2, 0.5Nx1, 1Nx1, 2Nx2, 5Nx1, 10Nx1
  • Deflection Graduation: 0.01~10mm
  • Bending Distance: up to 100mm, can be specified when ordering
  • 3 point Sample fixture: Ø3.0mm
