High-temperature Compression Stress Relaxation Tester: Precision Analysis for Rubber Material Performance
The High-temperature Compression Stress Relaxation Tester is a specialized instrument engineered to evaluate the compression stress relaxation characteristics of vulcanized and thermoplastic rubber specimens. Its core functionality lies in simulating real-world conditions where rubber components are subjected to sustained compression over time, particularly under elevated temperatures. The testing process involves compressing specimens to a constant strain state—both at room temperature and high temperatures—and measuring the gradual reduction in compressive force over extended periods. This data reveals how rubber retains its elasticity and load-bearing capacity under prolonged stress, making it critical for designing durable products in industries ranging from automotive to aerospace.
The tester adheres to a suite of globally recognized standards, ensuring its results are accurate, comparable, and trusted across international markets:
- ASTM D6147: American Society for Testing and Materials standard for rubber property testing under compression stress relaxation, widely adopted in North American manufacturing.
- ISO 3384: International Organization for Standardization guideline for rubber, vulcanized or thermoplastic—determination of compression stress relaxation, essential for cross-border trade and research collaboration.
- GB/T 1685: Chinese National Standard specifying methods for rubber compression stress relaxation testing, critical for compliance in domestic industries.
By aligning with these standards, the tester guarantees reliability in quality control, material development, and regulatory compliance, making it an indispensable tool for laboratories and production facilities worldwide.
Intuitive Operation
Equipped with a color LCD touchscreen featuring a user-friendly human-computer interface, the tester simplifies complex testing workflows. Operators can easily set parameters such as temperature, strain level, and test duration, while the interface displays real-time data—including compressive force, temperature, and elapsed time—in digital format. This intuitive design minimizes training requirements and reduces the risk of operational errors, ensuring consistent results even with less experienced users.
Advanced Data Management
The tester includes an automatic U-disk storage function that captures raw data throughout the test, eliminating the need for manual recording. This feature ensures data integrity by preserving time-stamped measurements of force reduction, temperature fluctuations, and strain levels. Additionally, flexible export capabilities allow users to transfer data to computers for further analysis, report generation, or long-term archiving—streamlining compliance documentation and research workflows.
Safety & Environment Control
- Protective Operation Chamber: The testing chamber is equipped with a safety shield to prevent contact with high-temperature components, along with integrated exhaust and cooling functions. These features maintain a safe working environment by dissipating heat and fumes, particularly during extended high-temperature tests.
- Comprehensive Electrical Protection: Built-in safeguards against over-current, over-voltage, under-current, and under-voltage conditions prevent damage to the tester and specimens, ensuring uninterrupted operation and extending equipment lifespan.
Precision Engineering
The tester’s design prioritizes accuracy in both temperature control and force measurement. Independent temperature regulation for each test station ensures that specimens in multi-group tests experience uniform or customized thermal conditions, while forced air circulation guarantees consistent heating throughout the chamber. This precision is critical for isolating variables and obtaining reliable stress relaxation data.
The High-temperature Compression Stress Relaxation Tester is indispensable for evaluating rubber materials in industries where long-term performance under compression is critical:
- Automotive Manufacturing: Testing rubber gaskets, O-rings, and seals used in engines and braking systems, where resistance to stress relaxation prevents leaks and component failure.
- Aerospace: Evaluating rubber components in aircraft engines and hydraulic systems, which endure extreme temperature fluctuations and sustained compression.
- Industrial Machinery: Assessing vibration dampeners, conveyor belt rollers, and hydraulic seals, where material degradation under stress can disrupt operations.
- Consumer Products: Analyzing rubber parts in appliances, such as door gaskets in refrigerators, to ensure longevity and energy efficiency.
- Multi-station Flexibility: With 3 or 6 optional test stations, the tester enables simultaneous evaluation of multiple specimens—ideal for comparative studies of different rubber formulations or batch quality checks.
- High-Temperature Accuracy: The temperature range of ambient +10℃ to +200℃, combined with 0.1℃ resolution, allows precise simulation of extreme operating conditions, from mild ambient environments to high-heat industrial settings.
- User-Centric Design: The compact overall dimensions (1100×700×580mm) make the tester suitable for laboratory environments with limited space, while manual loading for deformation (0–12.7mm) ensures ease of specimen setup.
In summary, the High-temperature Compression Stress Relaxation Tester combines advanced control systems, safety features, and compliance with global standards to deliver accurate, actionable data on rubber performance. Whether used in material research, quality control, or regulatory testing, it provides the insights needed to develop durable, reliable rubber products that withstand the demands of real-world applications.
