SBR Latex for Carpet Backing: How to Evaluate Total Cost

For carpet manufacturers, SBR latex is an important raw material in carpet backing formulations. When evaluating different suppliers, the purchase price per kilogram is only one factor to consider.

A more complete evaluation can include latex consumption, total solids, formulation requirements, transportation and production conditions.

Price per kg vs. Cost per m²

Two SBR latex products may have different prices per kilogram while requiring different wet latex dosages.

Total solids is one of the key parameters.

When the target dry polymer content remains similar, a higher-solids latex may require less wet latex in the formulation.

Therefore, carpet manufacturers can compare:

Price per kg → Latex dosage → Dry polymer content → Cost per m²

This calculation can provide a practical reference when reviewing SBR latex suppliers.

Factors That Can Affect Carpet Backing Cost

The overall cost of SBR latex may also be influenced by:

• Total solids
• Latex dosage
• Filler loading
• Drying conditions
• Packaging
• Transportation
• Storage
• Production efficiency

For large-volume carpet production, even a small change in latex consumption can have an impact on annual raw material requirements.

Evaluating a New SBR Latex

Before changing suppliers, manufacturers can conduct laboratory and production trials using the actual carpet backing formulation.

Typical evaluation items include:

• Total solids
• Viscosity
• pH
• Coagulum
• Mechanical stability
• Foam behavior
• Adhesion
• Drying behavior
• Final carpet properties
