What is 9H tempered glass?

All of our screen protectors for sale at subtel.co.uk feature 9H tempered glass. But, what does this mean?

Firstly, let’s find out what tempered glass is.

What is tempered glass?

Tempered glass is used in security situations when hardness is needed and glass that breaks into sharp shards is undesirable - like in car windows or phone screen protectors. Unlike normal glass, tempered glass fractures into small, harmless pieces.

The process of tempering begins with a cut piece of glass that’s of high quality. Glass with imperfections and impurities will shatter under the tempering process.

There are two methods of tempering: heat treatment and chemical treatment.

Under heat treatment, glass is heated to more than 600 degrees Celsius. The glass then undergoes a high-speed, high-pressure cooling procedure.

In chemical tempering, the glass is bathed in chemicals that exchange ions on the surface of the glass in order to create compression.

In both methods, surface compression is created within the glass. While this surface compression does reduce the flexibility of the glass, it massively increases the amount of force needed to break it on a front-on impact - by around 5x that of untempered glass.

What does 9H hardness mean?

The Mohs hardness scale of minerals ranges from 1 to 10 - ranking the hardness of minerals such as talc (1H) and diamond (10h).

Hardness is measured by a mineral’s ability to scratch the surface of another. If regular glass scores a 5H on the hardness scale, it means it can scratch any other material under 5, but can itself be scratched by anything above 5.

Things that rate 9H on the hardness scale include sapphire and ruby - very hard things indeed.

By having a phone screen protector that’s 9H tempered glass, it means that it can both absorb impacts around 5x better than normal glass, whilst also offering the scratch protection of a material as hard as a sapphire.

Reliable protection when you need it

Our phone screen protectors offer 99.9% transparency for unparalleled image quality and usage, anti-fingerprint or smudge coating, bubble-free and water repellent application and scratchproof, shockproof and shatterproof protection.

All protectors are shipped within the UK from the day your purchase is made and come with a 3-year manufacturer’s warranty.

If for whatever reason you’re unsatisfied with the quality of our product, you can return it within 30 days.
