Phone protectors have been around for decades. The replacement of mobile phones is getting faster and faster. As soon as the phone is purchased, a protective film is attached to the screen. Although the development of mobile phone film is not as early as that of mobile phones, it has been decades.
We all know that the originator of the mobile phone screen protector is the first PP protective film material to appear on the market. It has the characteristics of hygroscopicity, acid and alkali corrosion resistance, and dissolution resistance, but also has defects such as low density, low transparency, low gloss and low rigidity.
Next is the PVC protective film. PVC material is soft and easy to paste, but this material is thick and has poor light transmission, making the picture appear hazy. It also leaves glue marks on the screen after tearing it off. It will also affect the display effect of the screen. With the change of temperature, there will be yellowish phenomena.
At seventies , we are most familiar with PET protective film, and PET protective film is also the mainstream mobile phone protective film material on the market. Better texture, more scratch-resistant, and less expensive. PET is an environmentally friendly and recyclable material. The texture is hard, the surface has strong anti-friction and scratch resistance, good light transmittance (above 90%), anti-glare, and avoids dust adsorption.
But with the needs of the times and the market, tempered film came into being. There are green light film, tea blue light film, privacy film, purple light film, etc. for people’s needs. For example, the tea blue light film has the properties of anti-blue light to protect the eyes; the green light film has the characteristics of anti-green light, and the privacy film has the function of protecting privacy. These are the most basic functions they have, such as explosion-proof, anti-drop and anti-fingerprint.
