(1) PE material
The main raw material of PE is LLDPE, which is soft and has a certain stretch. The general thickness is 0.05MM-0.15MM, and its viscosity varies from 5G-500G depending on the use requirements. Electrostatic film is a kind of protective film with no glue at all, of course, the adhesion is relatively weak, mainly used in electroplating and other surface protection. Mesh film is a kind of protective film with many grids on the surface. This kind of protective film is more breathable and has a more beautiful pasting effect, unlike the plain film which will leave bubbles.
(2) OPP material
OPP material is closer to PET film in terms of appearance, its hardness is larger and it has certain fire retardancy, but its pasting effect is poor, so it is rarely used in the market.
(3) OCA material
OCA protective film is no different from other materials in appearance, but OCA protective film is produced in Japan, and now it is the most used in Apple cell phones.
(4) PP material
PP material protective film is the first to appear on the market, the chemical name is polypropylene, without any adsorption capacity, generally with glue to stick, tear off will leave a glue imprint on the screen, a long time will corrode the screen. Now has been basically eliminated.
(5) PVC material
PVC material protective sticker is characterized by its own soft texture, and easy to paste, but this material is thicker, the light transmission is not good, so that the screen looks more hazy. Tear off will also leave a glue imprint on the screen. This material is also relatively easy to change with the temperature and commit yellow oil, the service life is relatively short.
(6) Improved version of PVC
PVC material improved version of the protective film, solve the previous thick and poor light transmittance of the problem. However, it still does not solve the problem of easy to turn yellow and oil, and PVC material does not have the ability to resist scratching, after a period of time there will be very obvious scratches on the protective film, affecting the display of the screen and the overall aesthetics of the phone. PVC itself is a toxic material, containing heavy metals, and has been completely stopped in Europe. This PVC modified version of the screen protector is more widely sold in the market, the price of this protective film is cheap, generally in the 10 yuan or so.
(7) PET material
PET material protective film is the most common type of protective film on the market, cell phones and tablet computers with this three-layer PET protective film. Chemically named polyester film. Features are harder texture, more scratch-resistant, long time use will not turn yellow like PVC material out of oil. The price of PET protective film is much more expensive than that of PVC. The use of PET material protection sticker sticker workmanship and packaging is more exquisite, there are special for hot buy cell phone models to customize the protection sticker, no need to cut can be used directly.
(8) AR material
AR material protection sticker is the best known on the market a screen protector, AR is a synthetic material, generally divided into three layers, silicone for the adsorption layer, PET for the middle layer, the outer layer of special treatment layer. The special treatment layer is generally divided into two types, AG treatment layer and HC treatment layer, AG is the anti-glare treatment, frosted type protective film is used in this treatment, HC is the hardness treatment, is the treatment of high light transmission type protective film. This kind of screen protector is characterized by non-reflective screen and high transmittance (more than 95%), which will not affect the display effect of the screen. The surface of the material is treated with a special process, and the texture itself is soft and has a strong anti-friction and anti-scratch ability. Long time use will not appear scratches, sticky chemical material silicone adsorption on the cell phone screen, so will not cause harm to the screen itself, tear off will not leave a mark, and can also be cleaned after reuse. The price is more expensive than PET material.
