Styrene Butadiene Rubber (SBR)
Reliable Performance Across Every Application
At GB Rubber and Gummi, we deliver top-quality elastomer solutions to meet your industrial and commercial requirements. One of our core offerings is Styrene Butadiene Rubber (SBR Rubber Compound) — a synthetic rubber known for its durability, flexibility, and excellent abrasion resistance.
Originally developed as an alternative to natural rubber, styrene butadiene rubber is now one of the most widely used synthetic rubbers in the world, utilized across a broad spectrum of industries.
Often compared with Neoprene, another popular synthetic rubber, SBR stands out for its reliable performance in dry, high-friction environments, making it indispensable in tire manufacturing, conveyor systems, and various mechanical applications.
Whether you’re looking for long-lasting gaskets or dependable belts, SBR’s well-rounded properties make it a versatile and dependable choice.
Properties of SBR Rubber Compound
Styrene Butadiene Rubber (SBR) is widely recognized for its balanced mechanical properties and adaptability across various industrial applications. Its molecular structure offers a unique combination of strength, flexibility, and resistance to wear, making it a reliable choice for both general-purpose and high-performance products.
Below are the key properties that make SBR a preferred material in multiple sectors:
Different Types of Styrene Butadiene Rubber (SBR)
Styrene Butadiene Rubber (SBR) is one of the most widely used synthetic rubbers in the world, with multiple variants designed to serve specific industrial and commercial applications. Unlike Neoprene, which is known for its excellent weather and chemical resistance, SBR is often chosen for its superior abrasion resistance, processability, and cost-effectiveness—especially in high-friction, dry conditions. Understanding the different types of SBR can help manufacturers select the right compound for their unique needs.
Emulsion SBR
(E-SBR) is produced through an emulsion polymerization process and is the most commonly used type of SBR. It provides good tensile strength, durability, and aging stability (when stabilized with additives). E-SBR is widely used in the production of tires, footwear, adhesives, and conveyor belts.
Solution SBR
(S-SBR) is created using solution polymerization, resulting in a purer product with improved molecular structure. It offers better rolling resistance, enhanced wet traction, and higher performance, making it a preferred choice for eco-friendly, high-performance tires that meet modern automotive standards.
Oil-Extended SBR
Includes the addition of processing oil, which makes the rubber softer and more workable during manufacturing. This type is commonly used in tire treads and industrial products where improved processability and reduced costs are important. Compared to Neoprene, oil-extended SBR provides better wear resistance in dry conditions but is less resistant to chemicals.
Cold SBR
Synthesized at lower temperatures, offers superior mechanical properties such as higher tensile strength, better elasticity, and enhanced wear resistance. It is ideal for applications demanding precision and durability, such as tire sidewalls and technical rubber goods.
Hot SBR
Produced at higher temperatures, has a higher molecular weight but generally lower strength and elasticity than Cold SBR. It is suitable for molded goods and applications where high mechanical performance is not essential.
Modified SBR
Blends are customized compounds that combine SBR with other rubbers, like natural rubber or butadiene rubber. These blends are engineered to deliver specific performance characteristics such as increased elasticity, weather resistance, or chemical tolerance. They are commonly used in automotive parts, specialty seals, and industrial applications where conditions vary.
