The Moving Die Rheometer MDR ELASTOGRAPH, a rotor-less vulcameter from GÖTTFERT
is the ideal solution to measure the viscoelastic behaviour of natural and synthetic
rubber compounds in plasticised state, either during vulcanisation or after vulcanisation
according to the ISO 6502, ASTM D5289 and DIN 53529.
The vulcameter can be equipped with choice of different test chamber designs from quasi,
to hermetically sealed test chambers in biconical, shore and paste versions, which depends
on the standard and material used. With the optional autoloader, multiple tests can be
performed fully automatically without user intervention.
During the testing, the instrument imposed a torsional load onto the sample by the rotational
oscillation of the lower half test die. The recording of the Torque value and phase angle vs
test time is carried out.
The MDR ELASTOGRAPH machine has a fixed standard deformation amplitude of +/- 0.5°.
Alternatively, it can also be equipped with a different deformation amplitude between +/-
0.1° and +/- 1°.
