MDR-A ROTORLESS RHEOMETER (Auto Feeding)

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, torques such as S’, S” and S*(@ML, @MH), curing time such as Ts1, Ts2, T10, T30, T50, T60 and T90,  loss angle or Tanδ etc.  Which  cover the sample’s stiffness and damping property.MDR-A Rotorless Rheometer is produced based on existing ISO 6502, ASTM D5089, GB/T 16584 and HG/T 3709.
