GB/T 1232.3-2021 specifies the method for determining the Delta Mooney value (ΔM) of unfilled oil-extended emulsion-polymerized styrene-butadiene rubber (e.g., SBR 1723) using a Mooney viscometer. This value represents the difference between the Mooney values measured under two different test conditions, providing a more sensitive reflection of the influence of oil content and distribution in such rubbers on their processing behavior.
