HDT Vicat Apparatus

HDT Vicat Apparatus for Polymer Thermal Performance Testing

Our instrument measures heat deflection temperature (HDT) and Vicat softening temperature for plastics and rubber with high repeatability. Built in‑house with CNC‑machined components and rigorous calibration, each unit complies with ISO 75, ISO 306, ASTM D648, and ASTM D1525. Flexible configurations, OEM options, and one‑to‑one support help teams make faster, confident decisions.

Test Methods and Standards (ISO 75/ISO 306, ASTM D648/D1525)

Support for ISO 75 (HDT) at 120 K/h and ISO 306 (Vicat) with adjustable heating rates, plus equivalent ASTM procedures. Interchangeable load sets and indenters, stable bath control, and high‑resolution displacement measurement preserve method fidelity across materials and formulations.

Product Range and Configurations

From compact bench‑top systems to multi‑station testers, the range covers routine QA and high‑throughput R&D. Choose oil bath or dry heating. Select manual, digital, or fully automatic operation. Fixtures are available for sheets, rods, and profiles. Tight temperature uniformity and low measurement uncertainty are maintained across models.

Multi‑station Models

Frames with 3, 4, or 6 stations deliver high throughput with independent channels for temperature, displacement, and load. You can mix HDT and Vicat stations in one frame to maximize flexibility in busy labs.

Control and Data Acquisition

Closed‑loop PID temperature control and high‑resolution sensors feed an intuitive interface for real‑time curves, automatic endpoint detection, and LIMS export. Create method templates for ISO/ASTM tests and lock parameters to ensure consistent execution.

Heating and Cooling Options

Configurable heating rates (50–120 K/h) and optional forced cooling help shorten cycle times. Oil baths provide excellent thermal stability, while dry‑heat setups simplify maintenance in clean or low‑contamination environments.

Load Sets and Indenters

Precision weights and hardened indenters are compliant with ISO and ASTM requirements. Quick‑change holders speed transitions between test methods, and traceable calibration blocks support routine verification.

FAQ

What is the difference between HDT and Vicat tests?

HDT measures the temperature at which a specimen deflects under load. Vicat measures the temperature at which an indenter penetrates a defined depth under load.

When should I choose an oil bath versus dry heating?

Oil baths offer superior thermal stability and uniformity. Dry‑heat designs reduce cleaning and are preferred where contamination control is critical.

How do I size the number of stations?

Match stations to expected daily throughput and method mix. Multi‑station frames allow parallel testing and can combine HDT and Vicat positions.
