Styrene-Butadiene (SBR)

Styrene-butadiene rubber (SBR) is a type of synthetic rubber that is produced by the copolymerization of styrene and butadiene monomers. It is one of the most widely used synthetic rubbers due to its excellent abrasion resistance, good resilience, and low cost. SBR rubber can be produced with various levels of styrene content, which affects its properties.

Properties

• High resistance to abrasion, making it suitable for applications subjected to wear and tear.
• Good resilience, allowing it to deform under stress and return to its original shape when the stress is removed.
• Relatively inexpensive compared to other synthetic rubbers making it an economical choice for a wide range of applications.
• Moderate resistance to weathering, ozone, and UV radiation.
• Good electrical insulation properties.

Applications

• Tires, hoses, and belts
• Seals and gaskets
• Roofing materials
• Conveyor belts
• Shoe soles, footwear, and sporting goods

Industries

• Automotive
• Construction
• Industrial
• Consumer goods

Its versatility, affordability, and balance of properties make it a popular choice for many applications where durability and cost-effectiveness are important factors.
