Rubber Testers

The MDR one Moving Die Rheometer (MDR) is a reliable, accurate, and easy-to-operate rotorless curemeter perfect for routine and standards-driven testing of rubber curing. The MDR one is configured for measuring curing profiles of rubber compounds under isothermal and non-isothermal test conditions at constant strain and frequency.The MDR one employs sealed biconical dies meeting all relevant ASTM, ISO, and DIN standards.The unique design includes an ultra-rigid test frame, direct drive motor, precision temperature control with optional cooling, available Autosampler, and intuitive Scarabaeus Control and Analysis software making it the ideal platform for QC or R&D environments.

Features:

• Unmatched data precision, accuracy, and reproducibility
• Robust, field proven torque transducer for high stability and reliable torque measurements
• Extremely rigid test frame for accurate compliance free data
• Available autosampler for simple unattended operation
• Pneumatic locking cylinders for repeatable sample sealing
• Powerful and intuitive Scarabaeus Software available in multiple languages & compatible with other manufacturers’ instruments
• User calibration and user replaceable seals

Virtually every aspect of a rubber material’s processing and performance characteristics is influenced by its rheological properties. TA Instruments provides a complete range of rotorless shear rheometers and curemeters to help you optimize processing, curing, and application performance.

All TA Instruments rubber rheometers are manufactured to exacting mechanical standards and with the latest measurement technology for the most accurate, reliable, and reproducible data available. Available automation systems allow for maximum unattended laboratory productivity in all test environments.

Relevant ASTM, DIN, and ISO standards are easily met, as are demands for advanced testing, making these instruments the ideal choice for quality control, analytical, and research needs.

The MV one Mooney Viscometer incorporates the latest measurement technology for the traditional Mooney viscosity, Mooney scorch, and stress relaxation measurement in the rubber industry. The MV one is a fully featured instrument configured for standard viscosity, scorch and stress relaxation (linear, logarithmic, ISO, Mooney Stress-relaxation Rate) testing of rubber compounds under isothermal test conditions at constant speed of 2 rpm. An optional continuously variable motor mode allows tests over a speed range of 0.1 to 10 rpm. The MV one Mooney Viscometer is equipped with low mass rotors that meet all relevant ASTM, ISO, and DIN standards. All TA Instruments rubber testing instruments are constructed on ultra-rigid test frames and include direct drive motors, precision temperature control and the powerful and intuitive Scarabaeus Control and Analysis Software.

The TA Instruments Automated Hardness tester and Automated Density tester streamline the measurement of cured rubber physical properties. These fully automated instruments test up to 30 samples for sequential, reliable, unattended measurement. Software-driven test set-up, data collection, and pass/fail criteria make these systems truly automated.

Sample preparation for RPA, MDR, and Mooney instruments is made safe and simple with the VS volumetric sample cutter. This dual-action pneumatic system allows for the preparation of uncured rubber specimens of a user-defined volume.

Preparing samples in this well-controlled fashion reduces operational variability, greatly improving overall experimental precision.

The VS comes standard with a closing pressure of 6 bar. The sample is first compressed to the user-prescribed thickness, then cut to the die diameter. The closing pressure, and sample volume are user adjustable. An optional booster is available to increase operating pressure to 8 bar for highly filled and stiff materials. Two handed operation and lateral guards guarantee safe operation at all times.
