The most commonly used mobile phone film materials are OCA, PET and AR. Among them, the mobile phone film made of OCA is better than other materials in terms of luminosity and hardness. This film was originally produced in Japan and is now the most popular material for mobile phone protective films. The PET film is the most popular material for mobile phone protective films. The texture is relatively hard, scratch-resistant, will not turn yellow and oil, and can be reused after cleaning. However, this kind of film relies on electrostatic adsorption, which is easier to foam and fall off. At present, the most common type of PET protective film on the market, many well-known foreign brand mobile phones are equipped with PET protective film when they leave the factory. AR material is currently the best screen protector on the market. The screen is non-reflective and has high transmittance. It has a soft texture and strong anti-friction and scratch-resistant ability. It adopts chemical silica gel adsorption and does not damage the screen. It can be reused after cleaning. The price is relatively low. PET is expensive. So, besides the above-mentioned three kinds of mobile phone film materials, are there any other mobile phone film materials? The answer is yes. Now let's talk about the advantages and disadvantages of various materials for mobile phone films in detail. First of all, let’s introduce the PP mobile phone film that first appeared on the market. As long as the component of this mobile phone film is polypropylene, this kind of film has no adsorption capacity. Generally, glue is needed to stick. This kind of film After tearing it off, there will be glue marks on the screen of the phone, and this kind of film will corrode the screen after being used for a long time, but this kind of film has now been eliminated. The mobile phone film made of PET is soft and has a certain degree of stretchability. This kind of film is a kind of protective film with no glue at all with electrostatic adsorption force as its adhesive force, but its viscosity is relatively weak, and it is mainly used for electroplating and other surfaces. The protective electrostatic film, the other is a protective film with many grids on the surface, which has better air permeability, beautiful paste effect, and no air bubbles. The mobile phone film made of OPP material has high hardness and has a certain flame retardancy, and the effect of pasting is poor. Now it is rarely used in the market. OCA mobile phone film is better than other materials in terms of luminosity and hardness. This film was originally produced in Japan and is now used most on Apple mobile phones. It is now the most popular material for mobile phone protective film. The main component of PVC mobile phone film is poly Vinyl chloride, this kind of membrane is soft, easy to stick, and cheap, but this kind of membrane is thicker and has poor light transmittance. There will be glue marks after tearing off, and it will turn yellow and oily with the change of temperature. Use Short life, no scratch resistance, obvious scratches, heavy metal components are toxic, this kind of film has been completely stopped in Europe.
