Superior Performance of SBS in Bitumen Modification and Market Insights LOSMAN (LSMChem) Offers Efficient Powdered SBS Solutions

I. SBS: The Key to Enhanced Bitumen Performance

SBS, as a high-performance thermoplastic elastomer, plays an indispensable role in bitumen modification, significantly improving the overall performance of asphalt pavements and meeting the high demands of modern traffic for road durability and safety. Its core functions are reflected in several key aspects:

1. Significantly Enhanced High-Temperature Rutting Resistance:SBS forms a stable three-dimensional network structure within bitumen, effectively increasing the softening point and viscoelasticity of the asphalt. This substantially enhances the pavement’s resistance to rutting deformation under high summer temperatures, extending the service life of roads.
2. Excellent Low-Temperature Cracking Resistance:The butadiene blocks in SBS impart excellent elastic recovery and flexibility to modified bitumen, allowing it to maintain good resistance to shrinkage cracking in cold winter environments, thereby reducing pavement distress.
3. Improved Fatigue Life and Durability:The formation of the polymer network enhances the cohesion of bitumen and its adhesion to aggregates, improving the pavement’s fatigue resistance and water stability, enabling it to withstand long-term traffic loads and harsh climatic conditions.

Studies indicate that an SBS content of typically 3%–4% can achieve an optimal balance between performance and cost, leading to a comprehensive upgrade of bitumen materials.

II. Market Supply and Demand Dynamics & The Advantages of Powdered SBS

As April 2026 progresses, the SBS market presents a complex interplay of supply and demand. While the first quarter saw an overall upward trend, the second quarter is characterized by capacity adjustments and cost pressures. Global leading manufacturers such as Sinopec, CNPC, LCY, LG Chem, Dynasol, Sunion, and Changhong remain dominant forces in the market. With the full commencement of spring infrastructure projects, demand for SBS in road bitumen modification remains robust, and market prices are holding firm, supported by crude oil and monomer costs.

In this context, LOSMAN (LSMChem) particularly highlights its offering of powdered SBS, which brings significant advantages in production efficiency and cost-effectiveness to clients:

• Efficient Dissolution and Dispersion:Powdered SBS possesses a larger specific surface area, which significantly shortens the dissolution and development time in bitumen, enhancing production efficiency and reducing mixing energy consumption.
• Uniform Modification Effect:Superior dispersibility ensures that SBS forms a more homogeneous polymer network within the bitumen, leading to more stable and reliable performance of the modified asphalt product.
• Operational Convenience:Powdered SBS is easy to measure and add, simplifying the production process and reducing operational complexity.
