Elastomer-Testing MV

MOONEY-VISKOSIMETER

The MOONEY VISCOSIMETER 91.22 is suitable for unvulcanized rubber compounds as well as samples of pure natural or synthetic rubber.

The material sample (consisting of 2 punched-out discs) is subjected to shear stress in a closed chamber by a constantly rotating rotor. The resulting torque is recorded at constant pressure, temperature and speed.

Good to know

The MOONEY VISCOSIMETER 91.22 offers user-friendly handling thanks to its sophisticated design, which enables precise measurement with minimum effort.
