From manufacturer’s view- what to consider before buying a tempered glass protective film

The world of smartphones is all about better specs, performance, and longevity. There is one addition that will help extend the life of your phone and keep it safe and secure. Tempered glass screen protectors are just what you need. There are a number of brands of tempered glass screen protectors on the market that promise different specifications and benefits to woo customers around the world. But which one should you choose? Don’t forget that every smartphone has its own set of needs, and not all tempered glass protective films are suitable for every screen. It is possible to lose money and damage your smartphone by making one wrong move. Does anyone out there want to take on such a risk? Precautions are necessary unless you rarely use your Smartphone or have millions to spend every time you go grocery shopping. Tempered glass protective films are one way to take these precautions.

How is the client going to decide? How will they decide whether to buy it or not? Well, there are ways to clear up your confusion, and SHAWEASE, as a rising star in the tempered glass protective film market, have some tips for you.

1. Scratch resistance and durability

When choosing tempered glass protective films, keep in mind that the product needs to be durable enough to handle blades, scissors, keys, and other sharp objects above the ground. The excellent-tempered glass will always be difficult to scratch. For these to be possible, manufacturing companies tend to concentrate on the base material, namely glass. The glass used to make cell phone screen protectors is mainly aluminumsilicate glass, giving the product its high quality and durability. As Aluminosilicate glass comes from different manufacturers, you will need to ask your manufacturer about the quality of the glass.

A majority of China’s screen protector manufacturers use Japanese Asahi Pin and Chinese High Alumina Glass in their production. It’s the maker’s passion and honesty that drive them to create better products, giving us the quality we demand on the market.

2. Hardness 9H - tough factor

Hardness is an important consideration when selecting a toughened glass screen protector. The hardness of tempered glass can be explained by comparing it to a lead pencil, where the screen is resistant to scratches thanks to a 9H pencil, which is a hard pencil made of carbon, which has a really tough carbon quality. Screen protectors require toughness to withstand all odds.

Technically, 0.33mm 2.5D Double Strength Tempered Glass is a good choice.

3. Oleophobic Coating

With the help of an oleophobic coating, a phone surface with a toughened glass screen protector can be anti-fingerprint and anti-oil. Oleophobic coatings are used on smartphones and screen protectors to repel oil. It can make materials fingerprint-resistant since it repels the oils produced by the skin. Nowadays, oleophobic coatings are one of the most important characteristics of tempered glass protective films. Globally, manufacturers use oleophobic coatings on touch screens to make smudge-resistant devices.

Generally, you will not be able to find oleophobic coatings in low-end tempered glass protective films, and if you do, those films will not be of good quality as the technology used to apply the coating is inadequate. Oleophobic coatings are often used on high-end glass to distinguish high-quality products. China’s tempered glass protective films wholesale market is flooded with a variety of quality and you need to do a lot of research and search to find the right suppliers or manufacturers.

4. Fits perfectly on your screen

Perfect craftsmanship always gives you the best result and the same is applicable for good-tempered glass film. A meticulous cut by an expert means your toughened glass screen protector gives perfect and full coverage. You just have to hold your phone and judge the size particularly some of the photosensitive holes where there is more reflection and when applied there will be no sign of a bubble. 3D Curved Full Cover Tempered Glass Screen Protector can give your phone that coverage.

5. Smooth touch and movement

Here’s another factor to take into account when you’re looking at the quality tempered glass. When your fingers brush against or touch or slide across the surface of the tempered glass protective film, it provides you with a soft, smooth feeling. It feels much better, and much more, than the feeling you get when touching the original cell phone screen.

On the other hand, cheap quality scratch guards are made of almost rough glass film, not smooth enough and it gives you a kind of sticky feeling when you slide your fingers over it.

6. Protective shatter-proof design

As a rule of thumb, a toughened glass screen protector will keep you from shattering your phone if it accidentally falls on the ground and hits it hard. Therefore, if your phone falls from a certain height, you won’t be injured by broken pieces of glass.

Fragments of a shatterproof glass membrane won’t fly out, preventing secondary damage. It’s like a car windshield, the only difference is that glue matters here. It’s the same as a car windshield, but here the glue matters. Bulk tempered glass protective film suppliers and manufacturers in China do not always provide this feature, but some high-end membranes manufacturers do.

You can do this small test to determine if the phone’s membrane is functioning properly or not. We call it the Drop test – let a drop of a waterfall fall on the flat membrane of a mobile phone; if the water drops have an angle below 110, the steel technology of the mobile phone membrane is not very good. To our consumers, we always recommend they take this ‘Drop Test’ before purchasing a phone. Be sure to pick the one where the shape of the drop remains relatively rounded.
