What materials does the screen protector have?

<p>The <a href="https://www.jhjeanhon.com/screen-protector" rel="noopener noreferrer" target="_blank">screen protector</a> is a kind of transparent medium. At present, PET is mainly used as the raw material. The raw materials are mainly divided into Taiwan and Japan. The ordinary screen protector only plays a role of anti-dust. The better one has a crystal anti-scratch The coating can prevent scratches. The best screen protector is to incorporate metal elements to isolate electromagnetic waves and reduce electromagnetic radiation. At the same time, it can also reduce the dazzling feeling of watching the screen for a long time. It can also be used for Effectively protect the computer screen from scratches or cuts.</p><p><br></p><p>PP material</p><p>The protective film made of PP is the first to appear on the market. Its chemical name is polypropylene. It does not have any adsorption capacity. It is usually glued with glue. After tearing it off, it will leave a glue mark on the screen, which will corrode the screen for a long time. This material has been basically eliminated by the majority of protective film manufacturers, but there are still some merchants selling it.</p><p><br></p><p>OPP material</p><p>The protective film made of OPP material is relatively close to the PET protective film in appearance. It has higher hardness and certain flame retardancy, but its sticking effect is poor, and it is rarely used in the general market.</p><p><br></p><p>PVC material</p><p>The characteristic of the PVC protective sticker is that it has a soft texture and is easy to stick, but this kind of material is relatively thick and has poor light transmittance, making the screen look hazy. It will also leave glue marks on the screen after tearing off. This kind of material is also easier to turn yellow and oil out with temperature changes, and the service life is relatively short. So there is basically no such protective film on the market.</p><p>What you can see on the market is an improved version of PVC protective film, which solves the previous problems of heavy weight and poor light transmission, but still can’t solve the problem of easy turning yellow and oil, and it needs to pay attention to the material of PVC It does not have the ability to resist scratches. Obvious scratches will appear on the protective film after a period of use, which affects the display effect of the screen and the overall aesthetics of the phone. In addition, PVC itself is a toxic material and contains heavy metal components. , Has been completely discontinued in Europe. This kind of PVC modified version of the screen protector is widely sold in the market, and it is characterized by its soft feeling in the hand.</p><p><br></p><p>ET material</p><p>PET material protective film is the most common type of protective film on the market, and its chemical name is polyester film. The characteristic of PET protective film is that it is harder and more scratch-resistant, and it will not turn yellow and oil like PVC material when used for a long time. But the general PET protective film is electrostatic adsorption, which is easier to foam and fall off. , But even if it falls off, wash it in clean water and it can be reused.</p><p>The price of PET protective film is much more expensive than PVC. When many well-known foreign brands of mobile phones leave the factory, they are equipped with PET protective stickers. The PET protective stickers are more exquisite in workmanship and packaging. There are protective stickers customized for hot-buy mobile phone models. No cutting is required. Use directly.</p><p><br></p><p>PE material</p><p>The main raw material of PE protective film is LLDPE, which is relatively soft and has certain stretchability. The general thickness is 0.05MM-0.15MM, and its viscosity varies from 5G-500G depending on the requirements of use (the viscosity is different between domestic and foreign countries, for example, 200 grams of Korean film is equivalent to about 80 grams in China). The protective film of PE material is divided into electrostatic film and anilox film. The electrostatic film, as its name implies, uses electrostatic adsorption as its adhesive force. It is a protective film with no glue at all. Of course, it is relatively weak and is mainly used for surface protection such as electroplating. Anilox film is a kind of protective film with many meshes on the surface. This kind of protective film has better air permeability and a more beautiful paste effect, unlike plain weave film that will leave bubbles.</p><p><br></p><p>AR material</p><p>AR material protector is currently the best 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, and the outer layer is a special treatment layer. The special treatment layer is generally divided into two types, AG treatment layer and HC treatment layer, and AG is anti-glare Treatment, the frosted protective film is used in this way. HC is the hardness treatment, which is the treatment method used for the high light-transmitting protective film. The characteristic of this kind of screen protection film is that the screen does not reflect light and has high light transmittance (above 95%), which 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. There will be no scratches even after long time use. The adhesive is made of chemical silica gel which is adsorbed on the screen of the mobile phone, so it will not cause damage to the screen itself, will not leave a mark after tearing off, and it can be reused after cleaning. It is also easily available on the market, and the price is more expensive than PET.</p><p><br></p>
