9H hardness glass shatter-proof and scratch-resistant tempered glass

How much do you know about your screen protector?

Although screen protectors aren't entirely new to anybody today, there are some features of those accessories that many people do not know about.

A screen protector, as the name implies, is an additional sheet of material that is fitted to the display of an electronic device, like an iPhone, to protect it from physical damage. It is the first line of defense for a device screen.

Screen protectors are made of polyethylene terephthalate (PET) or thermoplastic polyurethane (TPU), or laminated tempered glass, similar to the device's original screen they are meant to protect.

Even more, screen protectors vary in hardness. You may have seen the hardness rating on different packaging. Nonetheless, if you don't know what this label means, then you're probably asking yourself, “What is 9h hardness?”

NEXT ONE designs screen protectors for iPhones and iPads made of 9H hardness tempered glass. 9H refers to the Moh scale of mineral hardness. Friedrich Mohs invented this scale in 1812, and it ranges from 1 to 10 with glass around 5 and diamond at the top of the scale.

The scale is represented by numbers only without the "H" suffix. The suffix means the hardness of a pencil. To find a rating, you use the pencil test, which compares the relative hardness of a screen. When a manufacturer claims that their screen is 9h, it means the screen can resist scratches from the hardest pencil.

A pencil hardness ranges from 9b to 9h. For testing various displays, you have to use pencils that have a lead hardness ranging from 6b to 9h, pressed against the surface at a 45-degree angle.

Smartphones usually come with screens that are around 5 to 6 on Moh's scale so that objects like knives, coins, and keys can't scratch them. This is because they're made of iron, copper, and steel, which cannot scratch glass screen protectors of 6.5.

Imagine adding extra protection of 9H to your device’s display - you can be sure that your device is safe in any circumstances.

The 9H hardness screen protector designed by NEXT ONE will protect the screen of your device from damage and allow very minimal to zero scratches to the screen protector. To get 9h screen protectors, check out our products for iPhone and iPad.
