Rubber Rheometer: Precise Analysis of Vulcanization Kinetics
In the rubber industry, consistency is key. A slight variation in the mixing process can ruin an entire batch of tires or seals. The Rubber Rheometer (Cure Meter) acts as the ultimate judge of compound quality, providing a detailed “DNA profile” of how the rubber cures. By measuring the torque required to oscillate a die within the rubber sample as it heats, the machine determines exactly when the material begins to cross-link (scorch) and when it reaches full cure.
Advanced Measuring Capabilities
This Moving Die Rheometer (MDR) offers a comprehensive suite of analytical tools:
- Precision Torque Measurement: Operates within a range of 0 to 250 dN·m with an exceptional accuracy of 0.01 dN·m. This sensitivity allows it to detect even minor changes in the compound formulation.
- Flexible Oscillation: Allows users to adjust the oscillation frequency (0.5 to 2 Hz) and select mechanical amplitudes (0.5°, 1°, or 3°) to suit different rubber stiffness levels.
- Thermal Control: Features a rapid-response heating system (Ambient to 250°C) with 0.1°C resolution, ensuring the sample is vulcanized under strictly controlled conditions.
Smart Operation and Software
Designed for the modern laboratory, the device includes:
- 7-inch Touch Screen: For quick setup and instant visualization of Cure Curves (Torque vs. Time).
- Pneumatic System: Automatic mold closure and a DC motor-driven protective door ensure operator safety and consistent pressure on the sample.
- PC Connectivity: Advanced software records critical data points like ts2 (Scorch Time), t90 (Optimum Cure), and MH/ML (Max/Min Torque) for reporting and quality analysis.
From Curing to Physical Testing
While the Rheometer determines how to cure the rubber, verifying the final physical properties is the next step. We recommend using our Universal Testing Machine (UTM) to test the tensile strength and elongation of your vulcanized rubber samples.
International Standards Compliance
This instrument is calibrated to meet the rigorous requirements of:
- ISO 6502: Rubber — Guide to the use of curemeters.
- ASTM D5289: Standard Test Method for Rubber Property—Vulcanization Using Rotorless Cure Meters.
