The difference between PET protective film and electrostatic film

Protective film is a kind of protective film product used in industry. It can be used for scratch-resistant, dust-proof, and waterproof protection of smooth exterior objects. PET protective film is widely used in hardware, plastics, backlight, diaphragm, light-enhancing film, acrylic Board and so on.

The function of the electrostatic film is the same as that of the PET protective film in large areas, such as anti-scratch, dustproof, and waterproof. The difference and the same part is that the PET protective film has electrostatic adsorption and viscosity adsorption.

Today we will come to understand the difference between pet protective film and electrostatic film

The PET protective film is divided into non-electrostatic adsorption and electrostatic adsorption. There are two-layer, three-layer structure and three-layer electrostatic protective film. The selected PET three-layer structure is one layer of release film + one layer of PET protective film + one layer of release For the film, the PET electrostatic maintenance film in the center layer is used, and the other two layers are used for maintenance. Now the PET film is generally scratch-resistant, and the so-called static electricity is silica gel.

Non-static adsorption mainly refers to the glue sticking. Although the sticking property is relatively strong, it is also prone to various problems. The first is that the glue remains, and the second is that after the film has been pasted long enough and then removed, the screen will feel insensitive to the touch due to the penetration of the glue. Relatively speaking, the phenomenon described above will not occur with the electrostatic adsorption film. The electrostatic adsorption method is based on the use of physical principles. When the protective film touches the LCD screen, the pressure in the air between the protective film and the LCD screen becomes smaller, making the atmospheric pressure stronger than the pressure of the air between the screen and the film. Absorption occurs. Electrostatic film is not only easy to post, but also easier to tear off.
