Also referred to 'safety glass', usually used in the applications requiring high impact strength, heat resistance, the process of Physical Tempered leaves the outer surface of glass in a state of compression, and the interior in a state of tension, and it will break into small pieces.
By our 'South' brand physical tempering furnace, we able to temper more than 8000M² glass per day.
The glass thickness below 2mm can not be fully physical tempered, however chemical strengthened will be a good choice. This technique is achieved through the process of ion exchange.
KS chemically strengthens soda-lime glass, non-glare glass and also high-ion exchange materials such as Dragontail, Corning Gorilla Glass.
The surface quality and flatness of the Chemical Strengthened Glass is better than Physical Tempered Glass, but Chemical Strengthened glass will not break into small pieces.
Chemically strengthened glass is typically used for thinner glass applications or applications requiring pristine surface quality such as an electronic displays or cover glass.
