Mooney viscometer

The Mooney viscometer is a shearing disc
viscometer, which permits to measurement of the Mo-
oney viscosity, Pre-curing (scorch), and Stress
Relaxation Characteristics of uncompounded or
compounded rubbers.
The test is carried out by measuring the torque,
which has to be applied under specified
temperature and pressure conditions, in order
to rotate a metal disc at 2rpm speed in the
cylindrical test chamber filled with rubber. The
the resistance offered by the rubber to this rotation
is expressed as the Mooney viscosity of the
test piece.
