The Fascinating Tale of 9H Hardness

Long before the great era of smartphones, the hero of our story was created and started his creative journey. At first, screen protectors were designed to shield television screens in the late 1960s. However, alongside the evolution of electronic devices, protective glass transformed from a bulky screen into a thin and sophisticated layer saving the screens of modern smartphones and other gadgets. This history reflects a simple fact – we need to protect our screens, and it has always been crucial for technological development.

Beyond the Surface: The Anatomy of a Screen Protector

In our modern tech world, screen protectors are everywhere, yet their engineering genius often goes unnoticed. We never think about how this thin piece of 9H tempered glass is a silent guardian of our device. It does more than just protection: it perfectly replicates the tactile and visual experience of the original screen, ensuring that protection doesn’t come at the cost of functionality. With a tempered class, you can say goodbye to annoying bubbles or rainbow effects and enjoy your display as usual. 

Unraveling the Mystery of 9H Hardness

In a big bright world of protective coatings and screen covers, the term "9H hardness" stands out as a perfect balance between durability and strength. But do you know, what this name means, and why it’s exactly number 9? 

The Genesis of 9H Hardness: A Scientific Investigation

To understand the specifics of 9H hardness, we have to talk about the scale according to which it was measured. Friedrich Mohs invented the scale of mineral hardness in 1812. It organizes different materials according to their resistance to scratching and other forms of harm. The hardest substance ever discovered naturally is diamond, marking 10 on its level of hardness at the topmost position of this scale. On another side is talc – the softest mineral with a level 1 degree on the same scale as diamonds’. 

While the number “9” explains a level of hardness, the letter “H” represents the hardness of a pencil capable of challenging the glass without leaving any marks. 

The Pencil Test: A Dance of Durability

To start this test, screen protectors have to be taken against pencils whose hardness varies from B6 to H9, and each pencil should be pressed upon the screen at an angle of forty-five degrees (45). The rating “9H” means that it can withstand scratches made by what is considered to be the hardest pencil.

These days, when mobile phones have become an important part of our everyday lives, we want to be sure about the safety of our devices. According to Mohs' Scale of Hardness, phone screens without any added protection fall between levels 5 and 6. That makes them resilient to common threats like keys or coins but doesn’t guarantee safety from smashing or cracking. That’s why it’s important to invest in a high-quality screen protector.

Tempered Glass: The Champion of Screen Protectors

In the quest for perfect screen protection, 9h tempered glass stands out as the best option, offering you a perfect combination of clarity and safety. This material was created through a rigorous tempering process, which ensures that it will take the hit to protect the screen of your device

The Verdict: Embracing the Shield of 9H Hardness

The story behind the 9H hardness screen protectors is not just about technological achievements, it’s a portrayal of our big connection with the gadgets. It represents our desire to keep them safe and comfortable to use. While we continue to explore new horizons and test new fascinating features of our devices, let’s not forget about these silent defenders that keep our phones safe. The next time you look at your perfect clean screen that doesn’t have any damage, think about the science, history, and innovations that were put together to create this thin cover.
