General Properties

Styrene-butadiene rubber, or SBS, defines synthetic rubber family and it is reproduced from styrene and butadiene. These synthetic rubbers, along with various additive substances, demonstrate excellent abrasion and aging resistance. Therefore, they are used as natural rubber in automobile tires and shoe soles. Rubber’s chemical and physical properties vary depending on styrene and butadiene amounts. Styrene, when polymerisied, is a hard plastic and it gives SBS its resistance. Butadiene has a rubber-ish structure and it allows SBS to gain gain rubber-like properties.


SBS is acquired through copolymerisation of styrene and butadiene monomers. There are two methods preferred for this; emulsion and solution. Emulsion method is consistent and more budget-friendly than solution method. Although solution method is more expensive, it allows to extract the exact desired result.


In today’s chemistry, SBS rubber has the highest volume in sythetic rubber field. It is used in automotive tires, shoe soles and heels, propulsion drivers and automotive components. SBS is also commonly used in glue production.

SBS is also used in paper coatings. It is also used to achieve resistance, flexibility and imperviousness in waterproofing systems and gaskets.

Safety Measures and Toxic Values

SBS is not too dangerous for human health but it can be flammable and when it burns, it releases toxic chemicals. Therefore, it should be carefully handled when mixing it with oxidising chemicals.
