ActiveRubber, unvulcanized—Determinations using a shearing-disc viscometer—Part 2:Determinations of pre-vulcanization characteristics
未硫化橡胶 用圆盘剪切黏度计进行测定 第2部分：初期硫化特性的测定
Application Summary AI generated
This standard specifies the method for determining the pre-vulcanization (scorch) characteristics of unvulcanized rubber compounds using a shearing-disc viscometer (Mooney viscometer). It is applied in the rubber industry to measure the time available for processing and shaping rubber before vulcanization begins, ensuring consistent curing behavior in manufacturing. The test is critical for quality control in tire production, conveyor belts, and molded rubber goods.
