Teach you how to identify the material of the protective film:

AR material: AR material protector is currently a better screen protector on the market. AR is a synthetic material, generally divided into three layers, silica gel is the adsorption layer, PET is the middle layer, the outer layer is the special treatment layer, and the special treatment layer is generally divided into two types, the AG treatment layer and the HC treatment layer, and AG is the anti-corrosion layer. Glare treatment, the frosted Henan Iwata spray gun protective film adopts this treatment method. HC is a hardness treatment, which is the treatment method used for high light transmission protective films. The characteristics of this screen protective film are that the screen is not reflective, and the light transmittance High (above 95%), will not affect the display effect of the screen. Moreover, the surface of the material is treated with a special process, and its texture is soft, and it has strong anti-friction and anti-scratch ability. It will not be scratched after long-term use. The adhesive is made of chemical silica gel which is adsorbed on the mobile phone screen, so it will not The screen itself causes damage and will not leave a mark after being torn off. It can also be reused after cleaning.

PP material: PP protective film is the first protective film that appeared on the market. This material is actually the material of the plastic bag we usually use. The chemical name is polypropylene. It does not have any adsorption capacity. It is usually glued. After tearing it off, it will leave a mark of glue on the screen, which will corrode the screen for a long time. Now this material has been basically eliminated by the majority of uv stepless dimming power supply protective film manufacturers, but some roadside stalls are still selling.

PET material: PET material protective film is currently the most common type of protective sticker on the market. In fact, the plastic Coke bottles we usually see are made of PET, also called PET bottles. The chemical name is polyester film. PET material protective film Its characteristic is that the texture is relatively hard and scratch-resistant. And it will not turn yellow and oil like PVC material after long-term use. However, the protective film of PET generally relies on electrostatic adsorption, which is easier to foam and fall off, but even if it falls off It can be reused after washing it in clean water. The price of PET protective film is much more expensive than that of PVC.
