Polarizing Film Product Search

After being dyed and stretched, a PVA film acquires polarizing characteristics to become a polarizing film. Dyeing materials are largely divided into iodine-type and dye-type.
Not only is Polatechno highly rated by customers for dye-type polarizing film, which is the field of our particular strength, but also for iodine-type polarizing film.

Transflective Polarizing Film

Polarizing Film

Transflective polarizing films are polarizing films equipped with both light transmission and reflection characteristics. This type of film can be used in various environments since display is possible in dark places by illuminating a backlight, while in light places the film's reflection function uses external light to display. A rich variety of products are available according to transmissivity, reflectivity, hues and textures. For samples, please contact Polatechno's Sales Department in charge of your area.

Reflective Polarizing Film

Polarizing Film

You can choose your desired reflective polarizing film from three kinds of polarizing films. Of these, the FSR-type film can make the background even whiter. By combining with a white-type polarizing film (KSW, SKE, AND or SHC-2 Series), it is also possible to obtain a lighter background which is close to paper white. For samples, please contact Polatechno's Sales Department in charge of your area.
