Application

Styrene butadiene rubber serves as a versatile material with a variety of applications due to its widespread use and adaptability. It can be found in either a solid or a viscous liquid state, depending on its degree of polymerization. This synthetic rubber is a key component in hot melt adhesives, sealants, asphalt, and oil gels. It is also utilized as a modifier for polymers, thermosets, and general rubber compounding. Additionally, styrene butadiene rubber is directly used in molded or extruded auto parts, sporting goods, footwear, and film production. Its synthesis involves the copolymerization of three parts butadiene with one part styrene, typically in an emulsified form with water, soap, or detergent, along with small amounts of initiators and chain-modifying agents. Notably, this rubber stands out as the most extensively used synthetic rubber, with its global consumption surpassing that of other elastomers.
