Product Description

 MR-C3 Rotorless Rheometer

The curves and characteristic parameters on vulcanization of rubber materials can be obtained using rotorless Rheometer based on the measurement of the torque exerted by the rubber material on the oscillating die.

The MR-C3 Rotorless Rheometer has excellent property of reappears and stability. In a test with good mixed rubber and the timerange is 12min, the T90 may be several second difference in 4 continual experiments.

MR-C3 Test Results

·M_L Min. torque (dNm)-The testing value of sample's curing characteristics (viscosity) before curing.
·M_H Max. torque (dNm)-The testing value of sample's shearing modulus or rigidity. Including even torque, max. torque for returning curve, and the max. Torque during the specific period of time where no even or returning curve happens.
·T_s1 (min)- when oscillates at the angle of 0.5° or 1°, the relative time when the torque increases to M_L +1dNm. This figure shows the scorch time.
·T_s2 (min)- when oscillates at the angle of 3° or 5°, the relative time when the torque increases to M_L +2dNm. This figure shows the scorch time
·T₁₀ (min)-The time when the torque increases to M_L + 10 (M_H - M_L ) / 100dNm. This figure shows the scorch time.
·T₃₀ (min)-The time when the torque increases to M_L + 30 (M_H - M_L ) / 100dNm.
·T₆₀ (min)-The time when the torque increases to M_L + 60 (M_H - M_L ) / 100dNm.
·T₉₀ (min)-The time when the torque increases to M_L +90 (M_H - M_L ) / 100dNm. This figure shows the optimum cure time.
·T_i (min)-The time when the torque increases to M_L + i (M_H - M_L ) / 100dNm.
·V_c-Curing speed index. V_c =100/(T₉₀ T_si)
