Rheoline ODR

The Rheoline Oscillating Disc Rheometer (ODR) is a curemeter that measures the dynamic properties of a rubber sample throughout the vulcanisation process. As stand-alone desktop instrument, the Rheoline ODR is a classic rubber testing instrument that has been used extensively in the polymer industry for many decades.

The Rheoline ODR is a rotor-based curemeter with a fixed oscillation angle and oscillation frequency that operates from ambient to 250 °C within an impressive range of ± 0.03 °C. With superior electronics, precision engineering and sophisticated Labline LIMS software, the Rheoline ODR can comfortably meet the demands of both Quality Control and Research & Development environments alike.

Many rubber testing professionals are already familiar with the working principle of the Oscillating Disc Rheometer yet require the efficiency and precision of a 21st century instrument. With the Rheoline ODR, Prescott Instruments have successfully meshed traditional testing techniques with the expectations of a modern rubber testing laboratory.

The Rheoline Oscillating Disc Rheometer is a stand-alone benchtop instrument that is supplied with Labline LIMS, the flagship software suite from Prescott Instruments. In addition, a programmable temperature zone module is available as an optional upgrade.

Key Benefits

  • The high-stiffness steel frame is durable enough to withstand the demands of a busy production environment with the precision performance to match.
  • Precision and accuracy to support the most critical applications
  • Rigid construction provides stability and reliability even when testing the hardest of materials.
  • State-of-the-art digital motor technology provides superior feedback control
  • The 16-bit PID has been exclusively designed by Prescott Instruments to deliver unparalleled temperature control to the highest levels of precision and stability.
  • Accompanied by bespoke high-end electronics for the highest data sampling rates available.

Mode of Operation

  1. A small rotor (disc) is embedded in a sample of rubber.
  2. The sample is placed between a set of upper and lower dies that form a sealed cavity. The sample is heated and held under pressure in this cavity.
  3. The rotor is oscillated through a small angle at a defined frequency, exerting a shear strain on the sample.
  4. The torque required to oscillate the rotor is read and recorded by the transducer. The torque signal is separated into two components – the viscous (loss) part and the elastic (storage) part.
  5. The calculated parameters are used to interpret the cure properties, mix and processability of a material.
