Choosing SBR Latex for Different Carpet Backing Applications

Different carpet constructions can require different backing formulations.

The suitable SBR latex depends on the carpet structure, filler system, coating method and required final properties.

Tufted Carpet

Tufted carpets may use SBR-based backing systems to bond yarn and backing materials.

Important considerations can include:

• Adhesion
• Flexibility
• Coating viscosity
• Drying
• Final hand

Carpet Tiles

Carpet tile backing may require specific strength, dimensional stability and processing characteristics depending on the construction.

The SBR latex should be evaluated together with the complete backing formulation.

Needle-Punch Carpet

Needle-punch carpet applications may have different bonding and penetration requirements.

Latex selection can therefore be based on the required bonding level and production conditions.

Secondary Backing

Secondary backing systems may require a balance between adhesion, flexibility and coating behavior.

High Solid SBR

For some formulations, High Solid SBR Latex can be considered when manufacturers want to review latex consumption and formulation water.

The most suitable SBR grade should be determined through laboratory and production testing.

RUICO supplies SBR latex for carpet backing applications and supports customers in selecting grades according to their formulation requirements.
