The rheometer measures the vulcanization strength required for the test specimen’s deformation. The term “rheometer curve” refers to the strength’s shift over time. These curves aid in assessing the rubber compound’s quality.

These are the testing curves and results for NextGen’s Oscillating / Automatic Disc Rheometer (ODR):

• ML – Minimum torque (dNm) – Measures value of the vulcanization characteristic (viscosity) of the unvulcanised test sample
• MH – Maximum torque (dNm) – Measures value of the shear modulus or rigidity of the fully vulcanized test sample. This includes the maximum torque of the flat curve and titration curve as well as the maximum torque when the flat and titration curves don’t appear within the given time.
• Ts1 (Minimum) – Time in which the torque is increased to ML + 1dNm when the swing angle is 0.5° or 1°
• Ts2 (Minimum) – Time in which the torque is increased to ML + 2dNm when the swing angle is 3°
• Ts10 (Minimum) – Time in which the torque is increased to ML + 10(MH-ML)/100dNm
• Ts30 (Minimum) – Time in which the torque is increased to ML + 30(MH-ML)/100dNm
• Ts60 (Minimum) – Time in which the torque is increased to ML + 60(MH-ML)/100dNm
• Ts90 (Minimum) – Time in which the torque is increased to ML + 90(MH-ML)/100dNm, reflecting the optimum vulcanization of your testing specimen
