What Is Low Iron Float Tempered Glass?

Low iron float glass also named Ultra-clear glass. It is made by matured technical operation norm. It looks just like colorless crystal with higher transmittance.


Compare to common float glass, it is with outstanding characteristics of the high solar lights transmittance, the low reflectance, the low iron, the high mechanical strength and the high flatness, it is the ideal encapsulation material for thin solar modules and thermal collectors.


Low iron float tempered glass is low iron float glass that has been processed through a tempering oven to increase its strength to resist impact, mechanical loads and thermal stress breakage. It is approximately four times stronger than annealed glass of the same thickness and configuration. When it is broken, tempered glass fractures into small fragments that reduce the probability of serious injury as compared to annealed glass.

Tempered Glass

Tempered glass is produced by heating glass to near melting point (approx. 650℃ and rapidly cooling the surface uniformly with air. Glass produced by this special process has enhanced strength and is used mainly for the rear and side windows of vehicles. It has the characteristic of fracturing instantly if broken.

 

Tempered glass is manufactured by generating compressive stress on the surface through quenching glass after heated to near melting point. When the glass is broken by tensile force, the force is counteracted by the surface compressive stress. Tempered glass is three to five times stronger than ordinary glass at the same thickness.

 

Tempered glass is strong. But if subjected to an external force that exceeds the limit of the compressive stress, it will fracture. Unlike ordinary glass, however, if broken, it fragments into small pieces. As there are no sharp, knife-like shards, it is unlikely to cause serious injury. That is why tempered glass is recognized as safety glass.
