Tempered Glass

We provide two types of tempered glass products for displays: physical tempered (heat-reinforcement) and chemical tempered glass. The chemical tempered glass made by Central Glass is particularly excellent for its processability after tempering. We have made it possible to efficiently produce smaller products by means of a cutting process after chemical tempering.

Physical tempered glass:
After tempering, it is not possible to cut glass with a thickness of 2mm or more.
Chemical tempered glass:
There are no limits on sheet thickness and it is possible to cut the glass after tempering.

Applications

Touch panels, cover glass for displays, platen glass for photocopiers, scanner glass, optical disks, magnetic disks
