Mobile phone film, also known as mobile phone protective film, mobile phone beauty film, etc., is a cold lamination film that can be used to mount the surface of the mobile phone body, screen and other tangible objects. The mobile phone film is mainly used to protect the screen of the mobile phone and prevent the screen from bursting, scratches, falls, etc. caused by various accidents. There are many kinds of mobile phone films. At present, the mobile phone film in my country is mainly divided into mobile phone tempered film, mobile phone hydrogel film and liquid nanometer. There are three types of mobile phone films. In recent years, with the continuous expansion of the scale of mobile phone users in my country, the market demand for mobile phone films has gradually increased, and the industry scale has continued to expand. It is expected that the penetration rate of smartphones in my country will exceed 80% by 2026, and the corresponding mobile phone film market is expected to grow to 31.7 billion yuan, of which the application potential of dimethyl silicone oil is huge!

After surface treatment, coating, coating, printing, plate making, calendering, galvanizing, lamination, film cutting, etc. on the mobile phone protective film substrate, it is endowed with strength, heat resistance, mechanical properties, electronic properties and optical properties. , gas barrier properties and other characteristics, it has become a high value-added functional film.
Depending on the function of the film, the required coating materials change accordingly. The coating materials include: hardening, anti-reflection, anti-glare, anti-static, fingerprint-resistant, self-healing, self-venting adhesive and pressure-sensitive adhesive, etc. According to its material, it can be divided into: mobile phone PC protective film, PVC protective film, PET protective film, AR protective film.
At present, the market demand for high-barrier films, photovoltaic films, power battery films, window films, protective films, optical films and other functional films is growing rapidly, and there is an urgent need for technological breakthroughs in domestic film processing and coating formulations.

What we are talking about now is one of the PET films of mobile phone films. In its production, a silicone material - polydimethylsiloxane, commonly known as dimethyl silicone oil, will be added. Polydimethylsiloxane is a kind of polysiloxane whose molecular chain is combined with silicon atom and oxygen atom with high bond energy and is not easy to break, commonly known as dimethyl silicone oil. The light transmittance of dimethyl silicone oil is 100%, non-toxic and tasteless, with physiological inertness, good chemical stability, and good high and low temperature resistance, generally can be in high temperature from 200 ℃ to -55 ℃ It can still work for a long time at low temperature.

In the coating industry, silicone oil is the most common release film. There are also many silicone products used in other process films, protective films, high-temperature tapes and mobile phone films, such as silane coupling agents, dimethyl silicone oil, and cross-linking agents. , anchoring agent, chloroplatinic acid, BPO and silicone resin, etc. Today, the application of silicone products in the domestic coating industry has been brought to the extreme, and glues with different viscosities and solid contents can be adjusted at will, suitable for all-weather coating operations of comma scraper, dimple and slit coaters, with no appearance. Crystal point, no snow pattern, high transmittance greater than 95%; no glue drop after high temperature and high humidity, low silicon transfer; fast exhaust, fast wettability; stable peeling force without climbing. There are many kinds of silicone products. Because of their unique functions and wide applications, they are an indispensable and important chemical material for national economic life.
