[China Glass Network] At present, there are many brands of glass film at home and abroad, and the variety of various film materials on the market is also very rich. What is a safety film? What is a security film, what are the differences between them? In general, there are three differences between security film and security film:
In front, from the structure and thickness of the material, the safety film generally uses a single layer of material, and the safety film adopts multi-layer film technology, and the ability to resist explosion is obviously improved. The thickness of the safety film is 100-175 microns (about 4 The security film is a multi-layer polyester composite film laminated by a special process and has a thickness of 250 micrometers (about 10 mils) or more. Thickness is a hard indicator that distinguishes between a safety film and a security film.
Second, compared with the protection concept, the safety film on the market generally has UV protection, heat insulation and scratch resistance to prevent the glass from damaging the splash. The safety film is designed to prevent or reduce the accidental breakage of the glass. It may cause harm to the human body. It can only prevent the glass splash problem caused by glass self-explosion, and the protection level is low. The design of the security film is to absorb the explosion shock wave and resist the impact of strong energy. The high-end security film and glass combination can even achieve the bulletproof level, and the protection function covers the security film effect while achieving the level of security.
Third, there is a clear distinction between the safety film and the security film in terms of implementation standards. The standard that can be achieved by safety film is based on the prevention of glass breakage. Most of these standards are to prevent "glass breakage". The safety film is to prevent the glass window from being broken when it is subjected to low energy impact; if the glass breaks, its residual film It still needs a large area to adhere to the safety film to prevent secondary damage caused by glass falling off. The security-grade explosion-proof membrane is generally treated to withstand the instantaneous impact of bomb explosions, bullets, etc. The detection standard of the security membrane is based on the prevention of penetration, that is, when the glass is hit, the glass can It is crushed, but the film cannot be penetrated.
