Emulsion Styrene Butadiene Rubber (E-SBR) - Types of Emulsion Styrene Butadiene Rubber

Emulsion polymerised styrene- butadiene rubber (E- SBR) is one of the most widely used polymers in the world today. Emulsion polymerised styrene- butadiene rubber is employed in many demanding applications, which enhance the quality of life and contribute significantly to our economy and standards of living.

Types of Emulsion Polymerised Styrene- Butadiene

There is a large variety of emulsion polymerised styrene- butadiene types based on the styrene content, polymerisation temperature, staining or non- staining antioxidants, oil and carbon black content. Each of these basic classifications include a variety of styrene- butadiene polymer variations with respect to Mooney viscosities, coagulation types, emulsifier type, oil levels, and carbon black types and levels. Table 1 shows the basic groups of emulsion polymerised styrene- butadiene.
