Description

>> Multi-function Rheometer MFR100A

Brief Descriptions:

Multi-function Rheometer MFR 100A is a newly-designed, based on the traditional rotorless rheometer, for testing the properties of rubber compounds. Besides the standard cure test per ASTM D5289, it's equipped with some utility functions to accurately reflect visco-elastic properties of rubber compounds further. These new functions, such as oscillating angles automatically switch-over, non-isothermal simulation cure test and frequency sweep test make users possible to widely use it in quality control, compounds research and development.  The latest temperature control system, advanced temperature probe and precise torque transducer as well as strict quality control manufacture, all these factors ensure MFR100A possessing excellent repeatability, reproducibility and sensitivity at the top level worldwide. Together with incorporating friendly graphical interfaces, powerful data processing capacity, and strong network function, it greatly improves users' testing capability, facility and efficiency.

Non-isothermal Cure Simulation Test:

Die temperature can be changed according to pre-set profile to simulate the temperature history during cure, especially for thick rubber parts, temperature varies dramatically during vulcanization.

Frequency Sweep Test Results correlate to Mooney Viscosity of Synthetic Rubber

According to ASTM D6204-Part A, 3-point Frequency Sweep Tests apply to batch release in quality control:

Test conditions: MFR100A TanDelta @ 0.5°(7%), 100℃(or 125℃), 0.1 Hz, 2Hz and 20Hz

One Multi-function Rheometer MFR100A 
can realize automatic switch-over
different oscillating angles to fit to 
different hardness of rubber compounds for avoiding slipping, 
improving sensitivity, and reducing 
instruments investment.
