Evergreenglass's Chemically Tempered Glass (CTG) is a type of glass that undergoes a specific treatment to enhance its strength and durability. The process involves subjecting the glass to a temperature below the glass transition point and then performing an ion exchange with molten salts, typically potassium salts. This exchange results in a surface compression and internal tension, which significantly improves the glass's resistance to thermal and mechanical stress compared to standard annealed glass.
Chemical tempered glass is not as strong as tempered glass, but it is more affordable and easier to process. It is also a safer option than tempered glass, as it does not shatter into small, sharp pieces when it breaks. CTG is often produced by heat treated glass suppliers and can be used in various applications as a type of custom architectural glass.

Increased Strength and Durability:
Chemical tempering strengthens the glass by roughly twice its original strength compared to annealed glass of the same thickness.
This makes it more resistant to breakage from impacts and scratches.
Improved Safety:
In the event of breakage, chemically tempered glass breaks into small, blunt fragments instead of large, sharp shards.
This significantly reduces the risk of serious injuries compared to regular glass.
Better Scratch Resistance:
The strengthening process creates a harder surface on the glass, making it more resistant to scratches and abrasions.
This is especially beneficial for applications where the glass is frequently touched or cleaned.
Enhanced Strength: Chemical tempered glass exhibits increased strength and resistance to mechanical impact compared to untreated glass. The compressive stress introduced during the ion exchange process strengthens the glass, making it less prone to breakage and more durable in demanding applications.
Flexibility: Unlike thermally tempered glass, which can exhibit a tendency to shatter into small fragments upon breakage, chemical tempered glass tends to exhibit more controlled breakage patterns. While still prone to breakage under extreme conditions, chemically tempered glass may produce larger fragments or remain partially intact, reducing the risk of injury.
Surface Compression: The chemical strengthening process creates compressive stress layers on the surface of the glass, providing enhanced resistance to scratches, abrasion, and surface damage. This surface compression helps maintain the optical clarity and appearance of the glass over time, even in high-traffic or harsh environments.
Optical Clarity: Chemically tempered glass maintains high levels of optical clarity, allowing for clear views and optimal light transmission. The strengthening process does not significantly alter the appearance or transparency of the glass, making it suitable for use in display panels, windows, and other transparent applications.
