IMPAdur®
Ceramic-printed glass automatically becomes toughened safety glass (TSG) through the stoving procedure that follows. This process makes our glass very durable and resistant to temperature changes.
Thermally tempered glass - precisely curved
A toilet flush plate made of IMPAdur glass, printed several times with ceramic colors, precisely bent and finished to TSG (toughened safety glass). We have developed a customized manufacturing process for series production for this application. With our thermally toughened IMPAdur glass, we offer the perfect solution for your requirements.
A material with endless diversity
Toughened safety glass (TSG) is not a type of glass, but thermally toughened glass in accordance with DIN 12150-2. For this purpose, flat glass is heated to approx. 630° C and the surface is then abruptly cooled by blowing air onto it. Our printed and functionalized glass undergoes this process automatically, as our ceramic colors have to be fired at approx. 630° to form an insoluble bond with the material.
Hardening of glass
Heating the material creates compressive stresses in the surface and tensile stresses in the glass volume. The compressive stresses make TSG significantly more resistant to temperature changes (200 K compared to 40 K for unhardened float glass) and, above all, significantly stronger — which is why the process is also known as “hardening”.
Broken glass without sharp edges
When cracks penetrate the glass volume due to excessive mechanical stress, the frozen tensile forces are suddenly released and the glass breaks down into small crumbs without sharp edges.
Applications
TSG is used, for example, for design panels to minimize the risk of injury due to broken glass. Glasses for HMIs are also generally tempered. Because of the tensions, tempered glass can no longer be mechanically processed.
