The purpose of a screen protector is to guard against various sharp things scratching the screen glass. It also has some degree of anti-shattering properties. The three primary types of screen protectors available on the market are tempered glass, TPU, and PET. They appear to be a very typical accessory, but are you truly aware of the variations in each substance, how it functions, and the outcomes it might produce?
TPU Screen Protector
Thermoplastic polyurethane, sometimes known as TPU, is a premium screen protector with oleophobicity, greater intensity, and scratch resistance. The TPU film can absorb a certain amount of impact energy while maintaining most or all of its original structure. It is an elastic material with certain “self-healing” properties. For instance, a minor scratch only causes a tiny pit on the film, and it will gradually go back to normal.
TPU screen protectors work better and offer superior impact protection than PET screen protectors. To improve its weather resistance and anti-yellowing capabilities, TPU screen protector is typically produced with the appropriate ultraviolet light absorbers. TPU film also has a superior sensation of touch, while not being quite as smooth as glass.
PET Screen Protector
The PET screen protector is a polyester film with a silicone adhesive on one side and a scratch-resistant matte coating on the other. Only nails, coins, and keys can harm a high-quality PET screen protector since it has brilliant transmittance and adds a scratch-resistant layer to the screen. PET film costs less, but it is more prone to color changes and becoming yellow from exposure to sunshine while in use, as well as being more susceptible to oil stains and having a less pleasant feel to the touch than glass.
Tempered Glass Screen protector
High-quality tempered glass films are made of several different layers of materials, starting with impact-absorbing silicone on the bottom, followed by PET film, a clear adhesive in the center, and then tempered glass and an oleophobic coating on top. All of the materials used to make scratch-, drop-, and oleophobic screen protectors are pressed into glass with a thickness of less than 0.4 mm. Glass film is typically a superior option when comparing performance to TPU and PET. Since it transmits more light, the screen appears clearer. Additionally, it is oleophobic, anti-reflective, and anti-glare, and it also has the smoothest feel.
