Rheoline MFR

The Rheoline Multi-Function Rheometer (MFR) is our most innovative dynamic testing rheometer, designed to deliver reliable results to the most precise accuracies with an extensive range of test stages or operations.
It is capable of fulfilling tasks of both a Moving Die Rheometer (MDR) and a Dynamic Shear Rheometer (DSR), providing vital analytical and statistical data of elastomeric properties to the finest detail, making this the ultimate choice for any polymer specialists.


Design conforms to ISO 6502 / ISO 13145 ASTM D5289 / ASTM D6048 / ASTM D6204 ASTM D6601 / ASTM 7605 DIN 53529 standards

Description

HIGHLIGHTS

This dynamic rubber testing instrument utilises a new generation In-line Servo Motor coupled with digital servo drive technology, together with our acquisition and analysis Labline Software; which has fantastic flexibility and provides a wide range of test conditions with unlimited’ test methods.

The temperature control of the dies gives an impressive variation of ± 0.03 °C from the set point. Should you require temperature assistance for operations like a Temperature Sweep, an Air Cooling System comes as an available upgrade or included in our Multi-Function Rheometer.

The instrument can be used firstly at lower temperatures and frequencies to study the process of polymers, secondly as a standard MDR and thirdly as a dynamic mechanical analyser to evaluate the cured properties of materials.

– A rheometer is a laboratory device used to measure the way in which a liquid, suspension or slurry flows in response to applied forces
– It is used for those fluids which cannot be defined by a single value of viscosity and therefore require more parameters to be set and measured than is the case for a viscometer.
