The Rheoline Moving Die Rheometer (MDR), or rotorless curemeter, is the rheometer most closely associated with the rubber industry. Instead of a rotor, a top and bottom die form a sealed biconical cavity that contains the rubber sample. The lower die oscillates through a small angle while the sample is held at an elevated temperature. The two dies allow the MDR to separate the elastic and viscous components of the rubber compound and plot them as two individual curves.
The MDR has grown significantly in popularity to become the industry-standard rubber testing instrument. It is possible to accurately determine the dynamic properties of a rubber compound before, during and after the curing process. Due to the sealed and pressurised cavity, the Moving Die Rheometer can measure these properties with excellent repeatability and shorter temperature recovery times.
The Rheoline Moving Die Rheometer is a stand-alone desktop instrument that is supplied with Labline, the flagship LIMS software suite from Prescott Instruments. An alternative model, the Rheoline Mini Moving Die Rheometer (MDR), is also available. Automation modules are compatible with both the Rheoline MDR and Rheoline Mini MDR, which permit the hands-free testing of up to 16 samples. See the Automation page for more details.
