SBR Latex for High Filler Carpet Backing Formulations

Fillers are widely considered in carpet backing formulations as part of cost and formulation design.

When filler loading increases, the interaction between the SBR latex and filler system becomes increasingly important.

What Happens When Filler Loading Changes?

Changing filler loading can influence:

• Formulation viscosity
• Mixing
• Foam
• Coating behavior
• Drying
• Adhesion
• Backing flexibility
• Final carpet weight

Therefore, the SBR latex should be evaluated together with the intended filler system.

Key Parameters to Review

Technical teams can consider:

SBR Latex

• Total solids
• Viscosity
• pH
• Mechanical stability

Filler

• Type
• Particle size
• Loading
• Surface treatment

Formulation

• Thickener
• Defoamer
• Water
• Mixing conditions

A laboratory trial using the actual filler system can provide useful information before a production trial.
