For applications such as mattresses and upholstered furniture, there are different requirements for the foam density, which is adjusted with the cell structure. One way to change the density is to add Calcium Carbonate, which influences the general cell structure and strengthens the cell walls.
Calcium Carbonate is available in a variety of particle sizes and particle size distributions, with its individual influence on the rheology of liquids. Omya specialists help PUR foam producers select the right product to achieve the best dispersion for homogeneous cell size distribution and strong cell walls, as well as the highest possible addition rates for high profitability.
