GB/T 1232.4-2017 specifies the method for determining the Mooney stress relaxation rate of unvulcanized rubber using a Mooney viscometer. After completing the standard Mooney viscosity test, the stress decay curve within a certain period of time (e.g., 30 seconds) after the rotor stops rotating is recorded. This parameter can reflect the relaxation characteristics of molecular chains in the rubber compound.
