Stüreenbutadieenkummi

Stüreenbutadieenkummi, often abbreviated as SBR, is a synthetic rubber that is a copolymer of styrene and butadiene. It is the most common type of synthetic rubber produced globally, accounting for a significant portion of the world's rubber consumption. SBR is known for its good abrasion resistance, cracking resistance, and aging properties, making it a versatile material for a wide range of applications.

The production of SBR typically involves the polymerization of styrene and butadiene monomers in an emulsion or solution process. The ratio of styrene to butadiene can be varied to tailor the properties of the final rubber. Higher styrene content generally leads to a harder and more rigid material, while higher butadiene content results in a more flexible and elastic rubber.

The primary application for SBR is in the tire industry, where it is used in the production of treads, sidewalls, and other tire components. Its excellent wear resistance and durability contribute to the longevity of tires. Beyond tires, SBR finds use in a variety of other products, including conveyor belts, shoe soles, hoses, gaskets, adhesives, and coatings. Its affordability and good performance characteristics make it an economical choice for many industrial and consumer goods.
