Sinterflex is a sintered porcelain slab produced through a high-temperature sintering process. Natural minerals such as clay, feldspar, and quartz are compacted under very high pressure and fired at high temperatures. This process increases the material’s density and mechanical strength without the use of resins or organic binders.
As a result, the panels provide high bending and impact resistance, near-zero water absorption, and superior resistance to UV exposure and chemical agents. The surface hardness is approximately 7–8 Mohs, and thanks to its fully inorganic structure, it has A1 class fire resistance.
