What You Should Look for in a Screen Protector

Screen protectors are numerous and getting easier to acquire and install. But what should you look for in a screen protector and what are the available options on the market? Let’s take a look at some of the most popular materials.

Polyethylene Terephthalate (PET) Film

This is your most basic screen protector on the market. They have a basic scratch resistant coating on one side of the screen protector with a silicone adhesive on the next side. They, however, offer no impact resistance or protection for your smartphone. Neither do they feel as good to touch as other material and they build up oils and get discolored from the rays of the sun. They can also impact the clarity of the viewing experience on your smartphone.

Thermoplastic Polyurethane (TPU)

This is plastic that has been chemically enhanced to offer grease and scratch resistance, and an added layer of impact protection. It feels better than its PET counterpart. But don’t get too carried away with the labels indicating that TPU is used in the protection of jet fighters. While this is true of TPU, there is no guarantee that you are getting the same level of quality in a screen protector.

Tempered Glass

This is by far the most popular type of material for screen protectors. The benefits have ben extolled and expounded at great lengths. High-quality tempered glass is a multi-layered screen protector that offers scratch, impact and oil resistance. Tempered glass is generally available in <0.4mm thickness and is as easy to apply as TPU and PET screen protectors. But what most persons don’t realize is that tempered glass is not shatterproof. Although tempered glass is strong, it will shatter and ultimately end up causing harm rather than preventing it. In fact, if the edges get damaged the entire glass may break.


Then there is shiellld. Shiellld is a screen protector that comes with propriety technology in the form of ArxTM. Together with the uniquely developed layers, Shiellld's screen protector absorbs and distributes impact across the screen protector. This makes Shiellld’s screen protectors shatterproof. Plus, they are 5X more durable than tempered glass and offer anti-glare features which help seeing the screen crystal clear under direct sunlight. It does all this in a thin cover of only 0.24mm that does not affect the quality or sensitivity of your smartphone’s 3D touchscreen.

What Should You Look for in a Screen Protector?

In conclusion, you should look for a screen protector that will not distort screen display quality, will hold up to impact, is shatterproof, thin enough not to affect screen quality but thick enough for maximum protection. When you compare impact performance of the various types of screen protectors - tempered glass, TPU, PET and Shiellld – Shiellld is clearly ahead of the rest.
