Thermal Deformation Vicat Softening Point Tester
Category:Textile Functional Tester
Introduction
This Thermal Deformation Vicat Softening Point Tester is a non-metallic material testing instrument designed and manufactured according to the latest international standards and national standards. It is mainly used for non-metal such as plastic, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high strength thermosetting laminates. Determination of the heat distortion temperature of the material and the Vicat softening point temperature. It is easy to operate and precise in control. Thermal Deformation Vicat Softening Point Tester is a highly intelligent test instrument widely used in colleges and universities, research institutes and product quality supervision and inspection units. It adopts single-chip control, PID phase-modulated output, with upper limit temperature setting, and automatically stops heating when the test temperature reaches the upper limit temperature..
Applications
plastic, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high strength thermosetting laminates.

FAQ
1. What is an Automatic Thermal Deformation Vicat Softening Point Tester used for?
It measures the softening point of plastics and polymers under controlled heating and load conditions.
2. How does the tester operate?
A heated bath raises the temperature at a controlled rate while a standard needle penetrates the sample, and the softening point is recorded automatically.
3. What types of materials can be tested?
Commonly used for thermoplastics, resins, and polymer-based materials to determine thermal deformation properties.
4. How is test data recorded and analyzed?
Data is collected automatically by the instrument, displayed digitally, and can be stored or exported for analysis.
5. What maintenance is required for the tester?
Routine cleaning of the bath and needle, inspection of mechanical parts, calibration checks, and software updates are recommended to ensure accurate results.
