SBR1502E - Emulsion Styrene Butadiene Rubber

Product Overview

SBR1502E is an environment-friendly emulsion styrene butadiene rubber manufactured by Lanzhou Petrochemical Company using low-temperature emulsion polymerization technology. This premium-grade synthetic rubber utilizes butadiene and styrene as monomers with potassium disproportionated rosinate soap or complex soap of potassium rosinate and fatty acid soap as emulsifier. The product is completely free from nitrosamines and salt, making it ideal for applications requiring environmental compliance.
