As the tile sector constantly evolves it is essential to have access to raw materials with specific properties suited to every manufacturing process. Our diverse product portfolio can meet all the mineral requirements of manufacturers producing the main types of tiles: Monoporosa, Monocottura, Gres Porcellanato and Porcelain Tile.
Raw material selection is not only determined by the end product type but also the properties required during the key stages of manufacture:
Grinding: optimum surface area, homogeneity, fluidity
Pressing: plasticity, tensile strength, shrinkage
Firing: vitrification, strength, shrinkage, thermal expansion, colour
We work with our customers to understand their goals before developing an optimum combination of body raw materials including:
Plastic materials: our range of refined and blended plastic clays and kaolins work to ‘bind’ a mass together so that it can be modelled and then hold its shape when dried.
Fillers: our specialist silicas control thermal expansion and shrinkage and also allow the body to breathe during firing.
Fluxes: Sibelco’s range of feldspathic minerals reduces the fusion temperature of the ceramic body and generally form glasses if heated to a sufficiently high enough temperature.
