What is SBR?

What is SBR? SBR stands for Styrene Butadiene Rubber; this is the oldest and most widely-used kind of synthetic rubber in the world. Worldwide, 65% of all rubber products are made of SBR, a fact largely due to its good mechanical and elastic properties. This grade of rubber is mainly used for car tyres, transport tyres and parts subject to a lot of wear in general. SBR is composed of butadiene rubber, complemented with between 10 and 35% styrene. The combination of these raw materials is what gives this rubber its excellent resistance to wear and ageing.

What is SBR?

SBR can be applied in practically all industries. This is because SBR is hardwearing as well as having high tensile strength and crack resistance. In addition, SBR has good resistance to friction wear. Admittedly, SBR is less flexible than natural rubber. To increase the flexibility of SBR, it is often blended with natural rubber.

SBR is tolerant of oil-contaminated air, water, industrial water and glycol. This grade of rubber can endure temperatures ranging from -50 to +100 °C and is suitable for damping, insulation and shock absorption. Material hardness varies between 30 and 95° Shore A.

The use of SBR is not advised if it is likely to come into contact with mineral oil, hydrocarbons, fuels or solvents. If you are looking for an oil-resistant grade of rubber, please take a look at NBR rubber.

What is the application of SBR?

SBR is used for indoor and outdoor applications such as anti-slip mats, supporting blocks in construction, the soles of shoes and car tyres. However, SBR can also be found in the building and shipping industries, as well as in industry at large. This material is used to prevent leaks or to air flow-through, among other things. SBR can therefore be used as an insulator or seal, or to absorb vibrations and shocks.
