Vertal® AF is a general-purpose talc/carbonate mineral additive, suitable for a broad range of applications, including polymers, ceramics, roofing, and asphalt. The benefits of Vertal® AF include improved dimensional stability, cross-flow mechanical performance, and flexural stiffness. It improves wet out of other additives and offers enhanced processability, improved crack and shrink resistance, and permeability reduction. The coarse particle size of Vertal® AF allows low dust, high bulk density, and minimum effects on viscosity of the melt/liquid media/carrier.
