Styreenibutadieenikopolymerit

Styrene-butadiene rubber, commonly abbreviated as SBR, is a synthetic rubber that is produced by polymerizing styrene and butadiene. It is a copolymer, meaning it is made up of two different monomers. The styrene component provides rigidity and resistance to oils and fats, while the butadiene component gives the rubber its elastic properties. SBR is known for its excellent resistance to abrasion, ozone, and weathering, making it a popular choice for various applications.

SBR is typically produced using emulsion polymerization, a process that involves dispersing the monomers in water and using a surfactant to stabilize the emulsion. The polymerization is initiated by a radical initiator, such as potassium persulfate, and the resulting polymer is then coagulated and dried to produce the final product.

SBR is used in a wide range of applications, including tires, hoses, belts, and seals. It is also used in the production of adhesives, coatings, and inks. SBR is available in various grades, each with different properties to suit specific applications. For example, high styrene content grades are used for applications requiring high resistance to oils and fats, while high butadiene content grades are used for applications requiring high elasticity.

SBR is a versatile and durable material that has been widely used in various industries for many years. Its unique combination of properties makes it an ideal choice for many applications where resistance to abrasion, ozone, and weathering is required.
