MDR-A Rotorless Rheometer

Available in: Finland , Sweden , Denmark , Norway

MDR-A is 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 ML,MH,ts1,ts2,T10,T50,T90,S’, S”, S*, Tanδ etc. which cover the sample’s stiffness and damping property.
