GB/T 41938-2022 stipulates the evaluation method of rubber compounding agent settling hydrated silica in the mixture of soluble polystyrene-butadiene rubber (S-SBR) and butadiene rubber (BR). The standard specifies the scope of application, covering mixing and vulcanization processes, as well as the determination process of key indicators such as Mooney viscosity, vulcanization characteristics, physical and Mechanical Properties, etc., standardizes test equipment, operation procedures and result analysis, and provides a unified standard for scientific evaluation of silica in rubber mixtures. Performance.
