The curves and characteristic parameters in the vulcanization of rubber materials can be obtained by using the rotorless Rheometer based on measuring the torque exerted by the rubber material on the oscillating die. MR-C3 Rotorless Rheometer has excellent recurrence and stability. In a test with well-mixed rubber and the time interval is 12 minutes, T90 may have a few seconds difference in 4 continuous experiments. 1. The instrument is easy to operate; MRC3 has automatic door and all electrical components comply with CE. 2. The temperature can be increased to 185℃ within 7.5 minutes, and the recovery time will be less than 2 minutes when starting the test. And the temperature fluctuation will be within 0.1℃. 3. All the instruments adopt PID way to control the temperature; 4. The smallest size and weight among all the instruments of the same type in the market; 5. The mold is designed according to the international standard ISO; 6. With lower noise when working, ≤55dB.
