Rubber testing machine Mooney viscometer 

 

MV-C3 Mooney Viscometer is used for measuring viscosity and relaxation of base rubber, 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 calibration, higher stability. It can perform the following tests: viscosity, scorch and stress relaxation.

Features
1. Easy to use the instrument.
MV-C3 have automatic door and all of the electric components are CE corresponding.
2. Temperature can be increased up to 185 within 7.5min, and recovery time when beginning, and recovery time when beginning test will be less 2min. And temperature fluctuation will be within 0.1.
3. All instruments adopted the way of PID to control temperature.
The smallest size and weight in all of the same type instrument in the market;
4. The die was designed to international standard ISO.
5. With lower noise when working, ≤55dB.

6. It is following  ISO 289 ,ASTM D 1646, JIS K 6300 .

7. Can variable Temperature unit “C, “ F  Degree.

8.Use window XP program connect to machine &  and  can  setting Mooney  or scorch time   and  show Dynamically Mooney value or scorch  time on  the  graph. 

 

Test Results

Measure of Mooney viscosity (Large rotor):

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

Stress Relaxation

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.

The value of exponent a,  the constant k,  the correlation coefficient r, and the  area A .
