See Chinese contents: GB/T 8655-2019 GB/T 8655-2019: Styrene-butadiene rubber (SBR) 1500, 1502
This Standard specifies requirements and test methods, inspection rules, marks, packaging, transport and storage for styrene-butadiene rubber (SBR) 1500,1502 [i.e., styrene-butadiene rubber, hereinafter referred to as styrenebutadiene rubber (SBR) 1500, 1502]. This Standard is applicable to styrene-butadiene rubber (SBR) 1500 and styrene-butadiene rubber (SBR) 1502 that take butadiene and styrene as monomers, compound soap of potassium rosin acid soap and fatty acid soap, or disproportionated potassium rosin soap as emulsifier, that is produced through low-temperature emulsion polymerization, where styrene-butadiene rubber (SBR) 1500 adds color-changing anti-aging agent and styrenebutadiene rubber (SBR) 1502 adds color non-discoloring anti-aging agent.
