D-MDR 3000

Rotorless, dynamical rotational shear Vulcameter with a closed test chamber systemmdr3000tisch_beleuchtet.jpg

  • The D-MDR 3000 is designed for measuring the viscoelastic properties of polymers and elastomeric compounds before, during and after cure. The acquired data is giving exact information about the processability, the cure characteristics, the cure speed, as well as the behaviour of the compound at the after-cure.
  • The D-MDR 3000 fulfils the complete range
    of all test requirements:
    Polymer or raw materials as well as basic, finished and cured compounds can be characterized. Besides the cure properties the cure characteristic and the processability can be determined and evaluated too.
