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.
Technical teams may review:
A change in SBR latex may require adjustments to the formulation depending on the filler system.
A practical evaluation can use the customer's actual filler and additive system.
The test can compare:
This approach provides application information that may not be available from a product specification sheet alone.
RUICO supplies SBR latex for carpet backing applications and supports formulation evaluation with different filler systems.
