tempered film generally refers to tempered glass mobile phone film. So tempered film is tempered glass film. Tempered glass (Temperedglass\Reinforcedglass) is safety glass. Glass has a very good wear resistance and hardness, whose vickers hardness has reached 622 to 701. Tempered glass is actually a prestressed glass, to raise the glass strength, usually using chemical or physical methods, to form compressive stress on the glass surface. When glass is under external force, first it will offset surface stress, so tempered glass improve the bearing capacity and enhance the wind load resistance, cold and heat resistance, and impact strength of glass. And tempered glass protective film is the most safest protection to mobile phone screen.
The difference between tempered glass color film and tempered glass film is that one frame is colored, the other is not. Tempered glass is actually a prestressed glass, to raise the glass strength, usually using chemical or physical methods, to form compressive stress on the glass surface. When glass is under external force, first it will offset surface stress, so tempered glass improve the bearing capacity and enhance the wind load resistance, cold and heat resistance, and impact strength of glass. While tempered glass protective?film can protect the screen of mobile phone effectively.
Difference between tempered glass color film and other phone protective film: Tempered glass is actually a prestressed glass, to raise the glass strength, usually using chemical or physical methods, to form compressive stress on the glass surface. When glass is under external force, first it will offset surface stress, so tempered glass improve the bearing capacity and enhance the wind load resistance, cold and heat resistance, and impact strength of glass. Other mobile phone protective films are generally composied of silica gel, PET and other material. Silica gel is absorption layer, PET is interlayer, and the outer layer is the special processed layer. Special process layer is generally divided into two types: AG treatment and HC treatment.
