Emulsion Styrene Butadiene Rubber is a styrene-butadiene copolymer rubber created by emulsion polymerization. It is extremely resistant to harsh conditions such as high temperatures, ozone, and sunlight. The tyre industry is the primary application of ESBR. Because of its properties such as heat stability, dynamic fatigue resistance, and good weatherability, Emulsion Styrene Butadiene Rubber is also used in a variety of other industries such as automotive, construction, and roofing. The emulsion styrene-butadiene rubber produced by the cold polymerization process is liquid. Because of its high flexibility, it is also known as water-based EBR and is commonly used for sheeting and coating applications.
Cold Polymerized Emulsion Styrene Butadiene Rubber (ESBR) production begins with the dispersion of monomers in an agitated reactor containing ionic or non-ionic surfactants under controlled temperature conditions, followed by polymerization via free radical chemistry with initiators such as peroxides.
