Rubber Mooney Viscosity Tester
The Rubber Mooney Viscosity Tester measures the viscosity of rubber under controlled temperature and shear conditions. A rubber sample is loaded into the viscometer cavity and preheated, then the rotor applies shear torque to the sample. The sample produces a resistance moment that is displayed either via a dial indicator or a connected computer, giving the Mooney viscosity value. This test is essential for evaluating processing properties and consistency of rubber compounds.
Applications
(1) Natural rubber and synthetic rubber: evaluation of processing viscosity for tire and automotive parts manufacturing.
(2) Rubber compounds: quality control during mixing and formulation.
(3) Footwear midsoles and outsoles: monitoring rubber flow and processability.
(4) Industrial rubber products: hoses, gaskets, belts, vibration dampers.
(5) Laboratory research: R&D on new rubber formulations and additives.
(6) Production monitoring: ensuring consistency of unvulcanized rubber batches.
Standards
(1) GB/T 1232 — Unvulcanized rubber: Determination of Mooney viscosity
(2) GB/T 1233 — Rubber compound: Determination of initial vulcanization characteristics — Mooney viscometer method
(3) HG/T 3242-2017 — Rubber Mooney viscometer
(4) ISO 289 — Unvulcanized rubber: Determination by shear disc viscometer
(5) ISO 667 — Rubber compound: Determination of initial vulcanization characteristics — Mooney viscometer method
Features
(1) Measures key processing property: quantifies rubber viscosity under controlled shear and temperature.
(2) Standard compliant: designed to meet GB/T, HG/T, and ISO requirements for Mooney viscosity testing.
(3) High precision: rotor speed and torque measurement are accurately controlled.
(4) Suitable for quality control and R&D: evaluates unvulcanized rubber and compounds.
(5) Easy data acquisition: torque readings can be displayed on dial or computer.
