ASTM-D1646 Rubber Testing Instruments Mooney Viscometer Machine
Product Overview
The Mooney Viscometer Machine is an instrument used for measuring the Mooney viscosity of substances, primarily elastomers and rubbers. It features a rotating spindle and heated dies, where the test substance encloses and overflows the spindle, with Mooney viscosity calculated from the torque on the spindle.

Test Results & Measurements
- Mooney Viscosity (Large rotor): MI - initial Mooney viscosity, ML - minimum Mooney value in last 30 seconds before motor stopped
- Mx-t: Mooney value relating to time t (x - preheat time, t - Mooney test time)
- Stress Relaxation: MRe - Mooney value at end of stress relaxation, TRx - time needed for x% torque stress relaxation
- Xy%: Percentage of viscosity decay after motor stopped y seconds
- Calculated Values: Exponent a, constant k, correlation coefficient r, and area A
- Graphical Output: Viscosity-Time curve, Test temperature curve, Mooney viscosity graph, Relaxation graph, Log Mooney units vs Log time graph
