Prescott’s Rheoline Moving Die Rheometer (MDR) has been designed to carry out, tried and proven test specifications in accordance with international standards. Providing fast, accurate data and meeting the requirements of a modern testing laboratory, the Rheoline MDR is ideally suited to both the production environment and for use in the development of elastomeric compounds.
Moving Die technology is a well-proven process that can significantly reduce your traditional testing and analysis times. At the heart of the Rheoline system is a rotor-less biconical die assembly with an internal cavity of 4.5 cm3. The lower die oscillates at 1.67 Hz over amplitudes of 0.5 °, 1.0 ° and 3.0 ° whilst the top die remains fixed and accurately measures the reaction torque, producing precise, repeatable data in an extensive range of testing environments.
The digital electronics module and 16-bit PID algorithm apply quick, accurate temperature control with a variation of ± 0.03 °.
Prescott Instruments have developed its own unique patented technology; an automated belt system designed to convey rubber samples into a test chamber, ensuring that the material under test remains in contact with the dies and reduces slippage.
In addition, programmable temperature zones and/or a pressure module is also available as an optional extra. Contact us for more details.
