GB/T 8657-2014 Styrene-butadiene rubber, raw—Determination of soap and organic-acid content
Abstract
This standard specifies two methods for determining the content of soap and organic acids in styrene-butadiene raw rubber: Method A is an indicator method, and Method B is an automatic potentiometric titration method.
This standard applies to emulsion-polymerized styrene-butadiene raw rubber. For styrene-butadiene raw rubber using aromatic hydrocarbon filler oil and/or obphenazine antioxidants, Method B should be used.
