Mineral fillers are commonly used in carpet backing formulations to adjust formulation cost, coating weight, density, and other properties.
When the filler loading increases, the compatibility between the SBR latex and the complete formulation becomes an important consideration.
A high-filler carpet backing system may require attention to:
The SBR latex should be evaluated together with the selected filler and additive system.
Changes in filler type, particle size, loading level, or formulation water content may influence the coating process.
For this reason, laboratory evaluation and production trials can help manufacturers identify a suitable carpet backing formulation.
RUICO supplies SBR latex for high-filler carpet coating and carpet backing applications.
