Glass Strengthening


Abrisa Technologies can strengthen glass via two methods, Heat Tempering or Chemical Strengthening. Depending upon your application, one method will be preferred over the other.
Chemical Strengthening:
The Chemical Strengthening process toughens soda lime through a sodium and potassium ion exchange in a salt bath. Glass can be strengthened from 8 to 16 hours and is often requested for toughened thin display applications. Chemical strengthening is best suited for thin soda lime sheets (under 3mm) and applications where optical distortion must be kept to a minimum. Chemically strengthened glass does not “dice” like fully heat tempered glass when broken.
Heat Tempering:
Heat Tempering toughens soda lime through the controlled heating and cooling of the glass to maintain a temperature differential between the core and outer surfaces. The stressed induced compress the outer surfaces, forming a substrate substantially tougher than standard soda lime. When broken, tempered glass “dices” into many small pieces. This is typically referred to as “Safety Tempering” for it’s reduced likelihood of cutting a person in the event of a fracture.
