The Advanced Solution for Weather-Resistant Thermoplastic Applications

Transform your products with Styrene Ethylene Butylene Styrene (SEBS), the hydrogenated thermoplastic elastomer that delivers superior weatherability and long-term performance stability.

Understanding SEBS (Styrene Ethylene Butylene Styrene)

SEBS represents the next generation of thermoplastic elastomers, created through the hydrogenation of SBS. This advanced polymer features saturated mid-blocks that provide exceptional UV and weather resistance compared to conventional styrenic block copolymers. The material's unique molecular structure combines the processing ease of thermoplastics with the performance properties of vulcanized rubber, while offering superior aging characteristics. Its excellent stability and resistance to degradation make it the preferred choice for demanding outdoor applications.

SEBS Classifications

General Purpose Grades

Our standard SEBS grades offer balanced performance with styrene content ranging from 13% to 30%. These grades provide excellent elasticity and processing characteristics, making them ideal for general compounding and polymer modification applications. Their consistent quality ensures reliable performance across various processing methods.

High Flow Grades

Engineered for injection molding and complex parts, these grades feature optimized melt flow characteristics. Available in various styrene contents, they excel in applications requiring detailed mold filling and efficient processing, particularly suitable for thin-walled products and intricate designs.

Oil Extended Grades

Specially formulated grades containing varying levels of process oil, offering enhanced softness and improved processing. These grades are perfect for applications requiring extreme softness and flexibility, such as soft-touch grips and gaskets.

Clear Grades

Our transparent SEBS grades deliver exceptional clarity while maintaining superior weather resistance. These specialized grades are designed for applications where both transparency and outdoor durability are essential, such as clear grips and translucent seals.

Applications in Modern Industry

SEBS has transformed various industrial sectors with its advanced properties. In the automotive industry, it serves as a key material for exterior and interior components, where its excellent UV resistance and durability ensure long-lasting performance. From weather seals to soft-touch surfaces, SEBS maintains its properties throughout the vehicle's lifetime.

The consumer goods sector extensively uses SEBS for soft-touch applications. Its excellent tactile properties combined with superior durability make it perfect for creating ergonomic grips, handles, and overmolded components that maintain their feel and appearance over time.

Medical device manufacturers rely on SEBS for its exceptional purity and stability. The material's biocompatibility and sterilization resistance make it ideal for medical tubing, seals, and various healthcare products where reliability is crucial.

In the construction industry, SEBS serves as a crucial component in roofing membranes and weatherable seals. Its outstanding weather resistance and flexibility ensure long-term performance in challenging outdoor environments.
