Summary:Aug 29,2026

Mineral fillers are commonly used in carpet backing formulations to adjust formulation cost, density and other properties.

Calcium carbonate is one example of a filler used in carpet backing systems.

When a high filler loading is used, the interaction between SBR latex and the filler becomes an important consideration.

Factors to Evaluate

Technical teams may review:

  • Filler type
  • Filler particle size
  • Filler loading
  • SBR latex solids
  • pH
  • Viscosity
  • Thickener
  • Mixing conditions
  • Foam behavior

A change in SBR latex may require adjustments to the formulation depending on the filler system.

Laboratory Testing

A practical evaluation can use the customer's actual filler and additive system.

The test can compare:

  • Mixing stability
  • Viscosity
  • Foam
  • Coating behavior
  • Drying
  • Adhesion
  • Final carpet properties

This approach provides application information that may not be available from a product specification sheet alone.
