Professionally tests Heat Deflection Temperature (HDT) and Vicat Softening Point (VST) of polymer materials such as plastics and rubber.
Complies with international standards including ISO 75, ISO 306, ASTM D648, ASTM D1525, and GB/T 8802.
In industries such as plastic products, wires and cables, automotive parts, and packaging materials, the heat resistance of materials directly impacts product quality and safety. The Heat Deflection and Vicat Softening Point Temperature Tester, as a core testing equipment, provides scientific basis for R&D, quality inspection, and production control by accurately measuring the critical deformation point of materials under heating conditions.
