Poraver® offers many possibilities for optimising products to make them lighter, with more yield, easier to use or more environmentally friendly. Our creamy white mineral lightweight aggregate offers densities from 190 kg/m³ and is available in different grain sizes from 0.04 mm to 4 mm. Thanks to its beneficial properties, Poraver® is versatile for different industries.
ROUND GRAINS FOR HIGHER PACKING DENSITIES
Among all particle shapes the spherical shape has the lowest surface area to volume ratio and therefore related advantages. Compared to irregularly shaped fillers higher packing densities and higher filler contents can be realized. The voids between the large Poraver® spheres are filled by smaller Poraver® grains, resulting in fewer gaps. This allows the reduction of binder and higher strengths can be achieved. More benefits
