What is the difference between tempered glass and toughened glass?

21 Feb.,2024

 

Tempered glass and toughened glass are actually the same thing, just different names for the same process. The process involves heating glass to high temperatures and then quickly cooling it to create a stronger, more durable glass. This process is what gives tempered glass its unique properties.

Tempered glass, also known as toughened glass, is four to five times stronger than regular glass of the same thickness. This makes it much less likely to shatter on impact, and when it does break, it shatters into small, dull pieces instead of sharp shards. This makes it a much safer option for use in buildings, cars, and other applications where safety is a concern.

The process of tempering glass involves heating the glass to around 620 degrees Celsius and then quickly cooling it with jets of cold air. This creates a state of high compression on the surface of the glass, while the interior remains in tension. This compression-tension balance is what gives tempered glass its strength and makes it more resistant to impact.

The benefits of using tempered glass are numerous. Not only is it safer, but it is also more resistant to thermal stress, making it ideal for use in applications where temperature fluctuations are common. It is also more scratch-resistant than regular glass, making it a great choice for high-traffic areas. In addition, tempered glass is easier to clean and maintain, as it is less likely to show fingerprints or smudges.

In conclusion, the difference between tempered glass and toughened glass lies in their names only. The process of tempering glass involves heating it to high temperatures and then quickly cooling it to create a stronger, safer glass. This process results in a glass that is significantly stronger and more durable than regular glass, making it a popular choice for a wide range of applications. Whether you are looking for safety, durability, or ease of maintenance, tempered glass is a great option for your next project.
