The MDR ELASTOGRAPH - S is a Moving Die Rheometer which is used to determine the viscoelastic material behaviour in plastified state during vulcanisation and after vulcanisation of the material sample according highest ISO and ASTM standards.
The ELASTOGRAPH, a rotorless vulcameter is used to determine the viscoelastic material behaviour in a plastified state during vulcanisation and after vulcanisation of the material sample. For that purpose, the torsional load is imposed on the sample by the rotational oscillation of the lower test die half. Torque and phase angle are recorded as a function of test time. The instrument can be equipped with five different test champers as well as different amplitudes. The GOETTFERT Moving DIE Rheometer is highly interesting for characterization of rubber compounds in plastic state, during vulcanisation as well as alreadt vulcanized samples. In contrast to the MDR Elastograph the -S model enables a higher deformation amplitude (0,1°-10°). The MDR Elastograph was developed with the experience of 45 years in the field of rubber testing and has proven high accuaracy, relaible and repeatable measurement results.
