1 What is window film?
Glass window film is a multi-layer functional polyester composite film material, which is processed by dyeing, magnetron sputtering, lamination and other processes on multi-layer ultra-thin and high-transparency polyester film.
It is mainly used for automobile glass and building door and window glass, partition glass, ceiling glass, etc., and it is pasted on the glass surface to improve the performance and strength of the glass, and to make it have the functions of heat preservation, heat insulation, energy saving, explosion-proof, beautifying the appearance, Covering functions such as privacy and security protection.
Second, according to the application field
According to different application fields, glass window films are mainly divided into three categories: architectural glass window film, automotive glass window film and safety glass window film.
Architectural glass window film is mainly used for doors, windows, ceilings, etc. of buildings, with the main purpose of energy saving and heat insulation, and has both UV protection and safety functions;
The car glass window film is pasted on the inner surface of the car glass, which has the functions of energy saving and heat insulation, UV protection, safety and anti-theft;
The main function of safety glass window film is safety and explosion protection, and it is generally used in financial institutions such as banks, jewelry store windows, museums, hotel halls or showrooms, etc.
Three points according to the process
Glass window film can be divided into three categories in terms of production technology: dyed film, primary color film, and vacuum coating.
Among them, the dyed film can be divided into ordinary film, surface dyed film, interlayer dyed film; vacuum coating can be divided into vacuum evaporation coating and magnetron sputtering coating; according to the different materials to be plated, it can be divided into metal film and ceramic film. .
