HDT/Vicat Testing Machine – Reliable Thermal Testing Equipment for Plastics, Rubber, Nylon & Insulating Materials Industry

📌 HDT/Vicat Testing Machine Overview

The HDT/Vicat Testing Machine is specifically designed to test the heat deflection temperature and Vicat softening point of non-metallic materials such as plastics, rubber, nylon, and electrical insulation materials.

This HDT/Vicat Testing Machine is widely recognized as a reliable thermal performance testing instrument for plastics, offering outstanding measurement precision. It complies with multiple industry standards, including GB/T 1633, ISO 75, and ASTM D648, ensuring accurate and reliable test results for a variety of materials. The device is also referred to as a heat deflection tester or Vicat softening point tester and is one of the key instruments for evaluating the thermal strength of materials.

The equipment features real-time temperature control, high-precision measurements, and a PID program-controlled heating system, ensuring safety and stability throughout the testing process. As a result, it is an ideal choice for evaluating the thermal properties of insulation materials, plastics, and rubber. The HDT/Vicat Testing Machine is highly recommended for use in chemical industries, research institutes, university laboratories, and quality control centers.

With increasing performance demands for high-grade polymer materials and engineering plastics, the HDT/Vicat Testing Machine has gradually become an indispensable standard instrument in quality evaluation and R&D workflows. It is not only suitable for standard bar-shaped samples for heat deflection temperature testing (HDT), but also capable of analyzing the Vicat softening point of various plastics, rubbers, and insulation materials, providing scientific data to assess material stability and performance limits under high-temperature conditions.

In new material development, formulation optimization, product certification, and production control, this type of polymer thermal testing equipment helps engineers quickly determine whether a material possesses heat resistance and anti-deformation capabilities. It is especially suitable for assessing and screening components in industries such as electronics, cables, automotive, building materials, pipelines, and home appliances—where mechanical stability under high temperatures is critical.
