Physical property

SBS,Styrene butadiene styrene block copolymer is a thermoplastic elastomer. Its obvious features include:


  • Excellent elasticity
    SBS exhibits the elasticity of rubber at room temperature, can be stretched and restored to its original state, and has good resilience and seismic performance.
  • Good processability
    As a thermoplastic material, SBS can flow during heating and solidify during cooling, making it easy to process and suitable for various plastic processing processes.
  • Weather resistance and oil resistance
    SBS has good weather resistance and is not easily affected by UV, ozone, and oxidation. At the same time, it can also resist the erosion of various oils and solvents.
  • Adjustable hardness
    By adjusting the molecular structure and composition of SBS, products with different hardness can be obtained to meet different application requirements.
Main uses

Due to its unique physical properties, SBS has broad applications in multiple fields:

    Shoe materials
    SBS is an important raw material in the footwear industry, used to manufacture soles and uppers. It can provide the elasticity, wear resistance, and comfort required for shoe materials.
  • 沥青.png
    Asphalt modification
    In road construction, SBS is used for asphalt modification, which can significantly improve the high-temperature stability, low-temperature crack resistance, and durability of asphalt pavement.
  • 胶黏剂.png
    Adhesives and pressure-sensitive adhesives
    SBS can be used as the main component of adhesives and pressure-sensitive adhesives, for making adhesive products such as labels, tapes, protective films, etc.
  • 轮胎.png
    Rubber products
    SBS can also be used to manufacture various rubber products, such as tires, seals, shock absorbers, etc., providing excellent elasticity and oil resistance.

In summary, SBS plays an important role in modern industry due to its unique physical properties and universal applications. We can confidently say that with the advancement of technology and the growth of demand, the application areas of SBS will continue to expand.

Comparison of differences and uses between SBS and SIS, SEBS, and SEPS

Differences from SIS:


Adhesion: SBS has relatively weak adhesion, while SIS has excellent adhesion performance. This makes SIS more suitable for producing adhesives and pressure-sensitive adhesives that require strong adhesion.


Application field: SBS has outstanding performance in the field of shoe materials and asphalt modification, providing wear resistance and resilience for shoe materials, improving the high-temperature stability and low-temperature crack resistance of asphalt. SIS is more commonly used for products that require long-lasting adhesion, such as labels, tapes, and protective films.


Differences from SEBS:


Modification ability: SBS is mainly used in the manufacturing of rubber products, providing good elasticity, wear resistance, and oil resistance. SEBS is mainly used for plastic modification, significantly improving the toughness, impact resistance, and low temperature resistance of plastics.


Application field: SBS is commonly used in the rubber industry, such as tires, seals, etc. SEBS is widely used in the production of plastic products such as automotive parts, home appliance casings, and toys.


Differences from SEPS:


Transparency: SBS typically does not have high transparency, while SEPS is known for its excellent transparency. This makes SEPS more suitable for products that require high transparency.


Application field: SBS is mainly used in the fields of rubber products and shoe materials. SEPS is widely used in products that require transparency, such as transparent adhesives, transparent labels, and transparent packaging boxes.
