The Superior Choice for High-Performance Thermoplastic Applications

Transform your product performance with Styrene Butadiene Styrene (SBS), the versatile block copolymer that combines rubber-like elasticity with thermoplastic processability.

Understanding SBS (Styrene Butadiene Styrene)

SBS represents an advanced thermoplastic elastomer that combines the best properties of rubber and plastic. This block copolymer features styrene end blocks with a flexible butadiene mid-block, creating a unique molecular structure that delivers outstanding elasticity with excellent processing characteristics. Unlike conventional rubber, SBS can be processed using standard thermoplastic equipment while providing rubber-like properties in the final product. The material's ability to be repeatedly softened by heating and hardened by cooling makes it ideal for various molding and extrusion applications.

SBS Classifications

Linear Grades

Our linear SBS grades offer balanced mechanical properties with styrene content ranging from 25% to 35%. These grades provide excellent elasticity and tensile strength, making them perfect for adhesives, sealants, and polymer modification applications. Their consistent molecular structure ensures reliable processing and end-product performance.

Radial Grades

Radial (star-shaped) SBS grades feature enhanced strength and improved processing characteristics. Available in styrene contents from 30% to 40%, these grades excel in applications requiring higher melt strength and superior mechanical properties, particularly suitable for polymer modification and compound applications.

High Styrene Grades

Specially engineered with styrene content above 40%, these grades deliver enhanced hardness and thermal stability. Perfect for applications requiring higher temperature resistance and improved dimensional stability, while maintaining good elasticity.

Clear Grades

Our transparent SBS grades offer exceptional clarity with balanced mechanical properties. These grades are specifically designed for applications where transparency is crucial, such as clear adhesives and optical products.

Applications in Modern Industry

SBS has revolutionized various industrial sectors with its unique properties. In the bitumen modification industry, it serves as a key polymer modifier, significantly improving the performance of road construction materials. The addition of SBS enhances asphalt's temperature sensitivity, elasticity, and durability, resulting in longer-lasting roads.

The footwear industry extensively uses SBS in shoe sole compounds. Its excellent wear resistance and flexibility make it perfect for creating comfortable, durable footwear components. The material's good processability allows for efficient production while maintaining consistent quality.

Adhesive manufacturers rely on SBS for producing high-performance adhesive formulations. The material's excellent tackifying resin compatibility and good cohesive strength make it ideal for pressure-sensitive adhesives, hot melt adhesives, and various bonding applications.

In the plastic modification sector, SBS serves as an impact modifier for rigid plastics. Its ability to enhance impact resistance while maintaining other desirable properties makes it valuable in engineering plastic compounds.
