ASTM D2084 Standard Test Method for Rubber Vulcanization Using Oscillating Disk Cure Meter

ASTM D2084 describes how to utilize an oscillating disk cure meter to assess certain vulcanization properties of rubber compounds that potentially vulcanize. The difference between the optimal vulcanization and the incipient scorch time is used to calculate the cure rate index, which measures the pace of vulcanization. The greatest slope of the torque versus time graph represents the peak cure rate, which measures the rate of vulcanization.

    Introduction to ASTM D2084

    Rubber compounds that can be vulcanizable have their vulcanization characteristics determined using ASTM D2084. This test technique can be applied to research and development as well as quality control in rubber production operations. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM D2084 tests for our clients. Testing of rubber compounded from raw materials in an assessment formulation and for assessing different raw materials utilized in the preparation of rubber compounds that can be vulcanizable.

    ASTM D2084 Test Method

    Setting up the specimenA test specimen made of vulcanizable rubber compound is kept at a high vulcanization temperature, sealed under positive pressure, and inserted into a cure meter test cavity.
    Shear strain applicationA biconical disk encircled by rubber oscillates with a small rotational amplitude, applying a shear strain to the test object.
    Measurement of shear strainAs a function of time and in proportion to the test specimen’s shear modulus (stiffness) at the test temperature, the force needed to rotate the disk is measured. When the measured torque reaches equilibrium or after a predefined amount of time, the test is declared finished. The properties of the rubber compound and the test temperature affect how long it takes to get a cure curve.

    ASTM D2084 Test Specimens

    Specimen DetailVulcanizable rubber compounds are test specimens for ASTM D2084.
    Specimen SizeA circular test specimen with dimensions of about 30 mm (1.2 in.) in diameter and 13.5 mm (0.53 in.) in thickness has a volume of 9.561.5 cm3 (0.5860.09 in.3).
