VST Apparatus (Vicat Softening Temperature)

VST (Vicat Softening Temperature) Apparatus is used to measure the temperature at which a plastic or polymer starts softening when a certain load is applied.

Its purpose is to check how heat-resistant a plastic is, to compare quality of different polymer materials, used in plastic, rubber, and material testing labs.

Features of VST (Vicat Softening Temperature) Apparatus

• Precise Temperature Control- Heating bath with uniform temperature rise (usually 50°C/hr ± 2°C).
• Digital Temperature Display- Shows real-time temperature with high accuracy.
• Standardized Indentor & Load System   - Uses a Vicat needle with predefined loads according to ISO / ASTM standards.
• Multiple Specimen Testing -   Many models allow 1–6 samples at a time.
• Automatic Data Recording - Records softening point, temperature, load, and deformation.
• Safety Features - Over-temperature protection and insulated bath.
• User-Friendly Operation - Easy specimen positioning and automatic test stop after softening.

Advantages of VST (Vicat Softening Temperature) Apparatus

• Determines softening point accurately - Helps to find the temperature at which plastics begin to soften under a standard load.
• Quality control of plastics - Ensures consistency and reliability of plastic materials during manufacturing.
• Simple and standardized test method - Operates as per ASTM / ISO standards, making results widely acceptable.
• Useful for heat resistance evaluation - Indicates how a plastic behaves when exposed to elevated temperatures.
• Applicable to many thermoplastics - Suitable for PVC, polyethylene, polypropylene, and other polymer materials.
• Good repeatability of results - Provides consistent and reproducible readings.

Applications of VST Apparatus

• Plastic manufacturing industry - Comparing heat resistance of different polymer grades.
• PVC pipe & fittings industry - Ensures pipes can withstand hot water and elevated temperatures.
• Electrical & electronics industry Used for insulation materials to check heat resistance.
• Automobile industryTesting plastic parts like dashboards, panels, and trims.
• Packaging industry - To ensure plastic packaging does not deform during heat exposure.
• Quality control & R&D labs - Comparing heat resistance of different polymer grades.

HDT Apparatus

HDT (Heat Deflection Temperature) Apparatus measures the temperature at which a plastic deforms (bends) under a specific load.
Its purpose is to know how much heat a material can withstand before bending and Important for selecting materials for high-temperature applications like automotive, electronics, and pipes.

Features of HDT (Heat Deflection Temperature) Apparatus

• Accurate Temperature Ramp - Uniform heating rate (typically 120°C/hr ± 2°C).
• High-Temperature Resistant Oil Bath - Ensures stable heat distribution for accurate results.
• Digital Dial Gauge / Linear Sensor - Monitors specimen deflection (0.25 mm or 0.32 mm depending on standard).
• Standard Flexural Loading System - Uses 3-point bending with fixed load weights.
• Multi-Station Testing - Allows multiple sample testing simultaneously.
• Microprocessor Control / PID Controller - Ensures precision in heating rate and test consistency.
• Automatic Data Acquisition (Optional) - Computer connectivity for storing and printing results.
• Safety Systems - Overheating cut-off and splash-proof bath design.

Advantages of HDT (Heat Deflection Temperature) Apparatus

• Measures load-bearing heat resistance - Determines the temperature at which plastic deforms under a specified load.
• Important for material selection - Helps choose suitable plastics for high-temperature applications.
• Simulates real service conditions - Tests deformation while material is under stress, closer to actual usage.
• High accuracy and precision - Controlled heating rate ensures reliable results.
• Compliance with international standards - Follows ASTM and ISO testing procedures.
• Widely used in R&D and industry - vital for performance testing and product development.

Applications of HDT Apparatus

• Plastic molding industries - Checks deformation temperature of molded plastic parts under load.
• Automobile industry - Used for testing engine-area plastic components.
• Construction industry - Testing plastic sheets, panels, and structural components.
• Electrical appliances industry - Ensures plastic casings do not bend during operation.
• Medical device industry - For heat-resistant plastic instruments and equipment.
• Research & material development labs - Evaluating new polymer formulations.
