Why Choose Keratec?
Pioneers in the world market, Keratec products are obtained from exceptional raw materials, which undergo a milling process of reduced granulometry and are formed by high pressure extrusion, and, finally, are fired at high temperatures, giving the product unique and high quality physicochemical characteristics.
Extruded Porcelain and Pressed Porcelain, which are the differences?
The lamellar structure that is a characteristic of the ceramic materials obtained by extrusion, results from the natural tendency of the clay particles to put themselves in layers during the extrusion process. The raw materials for extrusion are submitted to a grinding process by which a very reduced particles size is achieved, thereby increasing the density of the body (not fired yet) comparatively to the raw materials prepared to be used for pressed tiles. The smaller the particles are, the stronger is the reactivity between them, therefore lower the porosity of the final ceramic material.
