ActiveRubber, unvulcanized—Determinations using a shearing-disc viscometer—Part 3:Determination of the Delta Mooney value for non-pigmented, oil-extended emulsion-polymerized SBR
未硫化橡胶 用圆盘剪切黏度计进行测定 第3部分：无填料的充油乳液聚合型苯乙烯-丁二烯橡胶Delta门尼值的测定
Application Summary AI generated
This standard specifies the method for determining the Delta Mooney value of non-pigmented, oil-extended emulsion-polymerized styrene-butadiene rubber (SBR) using a shearing-disc viscometer. It is applied in the rubber industry for quality control and processability assessment of raw SBR materials, particularly to evaluate the curing characteristics and viscosity stability of oil-extended grades before compounding. The test helps manufacturers predict processing behavior during mixing, extrusion, or calendering operations.
