About the knowledge of mobile phone tempered glass film

Generally, the surface hardness of plastic film does not exceed 3H, the hardness of glass is about 6H, and the hardness of glass after tempering reaches 9H.


Tempered glass mobile phone film is a new mobile phone protective film introduced in the United States in 2012. It is the new high-end new product that protects the screen.


The thickness of this protective layer is only 0.4 mm, which can completely cover the original screen surface, prevent damage from external force, scratch, and increase shock absorption, which is 5 times higher than the standard of PET film. Does not affect the video effect of the screen. On this basis, the tempered glass oxygen eye film was introduced. On the basis of protecting the screen of the mobile phone, the blue radiation of the mobile phone is prevented from harming the human body, preventing myopia and achieving double protection of human and machine.


About tempered glass film raw materials: AB glue


What is AB glue? Because the tempered glass film can not be electrostatically adsorbed on the screen of the mobile phone like the ordinary plastic protective film, it needs to be applied to the inner layer of the glass film with a thin flexible double-sided adhesive tape. This thin flexible double-sided adhesive tape is called AB. gum.


About the thickness of tempered glass film


At present, there are four types of tempered glass film on the market: 0.4mm, 0.33mm, 0.2mm, and 0.15mm. These four thicknesses also refer to the thickness of the glass raw material. It has not yet included the previously mentioned AB glue. Generally, the thickness of AB glue is 0.085mm to 0.15mm (the brand of AB glue is different, the thickness is not the same). Then the thickness of the finished tempered glass film is at least 0.235mm, and the thickness of the product on the market is only the raw material. thickness.


Even so, the thickness is still a variety of virtual standards by various manufacturers. 0.4mm glass is marked as 0.3mm, 0.33mm is marked as 0.26mm, and 0.2mm is marked as 0.15mm. Even a lot of merchants directly mark 0.4mm directly as 0.1mm without any operation. (The thickness of 0.1mm is almost the same as the plastic protective film)
