MDR-A Rotorless Rheometer

MDR-A can be used for dynamic testing of the vulcanization rubber or rubber-like material. Curing curves and characteristic parameters can be obtained from MDR-A based on Fast Fourier Transform algorithm, such as MLMHts1ts2T10T50T90S, S, S*, Tan etc. which cover the samples stiffness and damping property.

The MDR-A Rotorless Rheometer is produced based on existing ISO 6502,ASTM D5089,GB/T 16584 and HG/T 3709.
