Functions:Prevulcanization,  Mooney Viscosity and Relaxation in one Machine!
MV-C3 Mooney viscometer is used for measuring viscosity and relaxtion of raw rubber stock or rubber mass prevulcanization properties. It is also used for measuring viscosity in Mooney value for compounded or uncompounded unvulcanized
natural,synthetic or regenerated rubber.
This instrument has excellent performances
including automatic save data, easy calibration,
easy operation and higher stability.It can perform
the following tests: viscosity,scorch and stress
relaxtion in one machine.

• Measure of Mooney viscosity / Stress Relaxation

MI -- initial Mooney viscosity.
ML - The minimum Mooney value in the last 30 seconds before the motor stopped.
Mx-t - Mooney value relating to time t.  x-the time of preheat, t-Mooney test time.
MRe - Mooney value at the end of stress relaxation.
TRx - time needed for x% torque stress relaxation.
Xy% - % of  Viscosity decay after motor stopped y sec.
