Selecting The Optimal SEBS for Carpet Backing — High Performance Meets Cost Efficiency

TOLLCHEM offers a comprehensive range of SEBS materials designed to meet diverse requirements in carpet backing applications. Depending on the production process and performance demands, different molecular structures of SEBS provide distinct advantages.

1. SEBS for Various Application Scenarios

• Low molecular weight linear SEBS features excellent flowability and low solution viscosity, ideal for high-speed coating processes. The resulting hot melt adhesive exhibits strong creep resistance and cohesive strength, making it suitable for hotel, exhibition hall, and other high-traffic commercial areas.

• High molecular weight SEBS retains superior mechanical properties even with high filler content such as calcium carbonate, perfect for thick carpet backing used in auditoriums, airports, and other heavy-duty flooring environments.

2. High Cost-Performance SEBS for General Use

TOLLCHEM’s medium molecular weight SEBS offers a practical balance between cost and performance. Through formulation adjustment, the hardness of the carpet backing can be precisely tuned. Its advantages include:

• Cost Competitiveness:
  The product is priced 5–10% lower than similar grades on the market. With excellent filler compatibility, the filler ratio can be increased by 10–15%, reducing unit cost effectively.

• Processing Advantages:
  With a moderate melt flow rate and wide processing temperature range (180–230°C), it adapts to different coating and extrusion lines, improving coating efficiency by about 15% and reducing energy consumption.

• Balanced Mechanical Performance:
  The finished backing achieves Shore A hardness of 70–80, ensuring firm tuft adhesion while maintaining a comfortable underfoot feel. It also demonstrates good water resistance and initial tack, lowering the risk of post-installation issues.

3. Application Versatility

This SEBS grade is suitable for residential, commercial, and public space carpet applications, offering the ideal combination of durability, comfort, and production efficiency.

TOLLCHEM remains committed to providing reliable polymer solutions and technical support to help customers optimize performance and cost in carpet manufacturing.
