SWITCHABLE PDLC FILM

This film used to switch between transparent and opaque state; hence it is known as Switchable film. PDLC (Polymer Dispersed Liquid Crystal) technology involves dispersion or dissolving or liquid polymer, which then solidified in the polymer by curing it. When this solidification process is taking place, the liquid polymer crystals begin to form individual droplets, as they become increasingly incompatible with the polymer. These droplets are built all over the polymer sheet almost in a uniform manner. The type of curing determines the size of the crystal droplets that form in the polymer, and also give it unique properties, thus allowing it to use in ‘Smart Windows.’

Usually, the mix consisting of polymer and liquid crystals placed between two individual sheets of PET (Polyethylene terephthalate) which also includes a fine layer of transparent and conductive material (ITO). Then the polymer is cured and forms the basic structure of the smart window. That acts as a functional capacitor.

This PDLC film then connects to electrodes from a suitable power supply. This Film turns transparent in ON condition and opaque in OFF condition. It can operate with the switch as well as with remote. The intensity of transparency can control with regulated remote control. When a voltage applied to this electrochromic film, the liquid crystals are pushed around in a random manner, which helps to disperse most of the light passing through it. The smart or magic film takes on a translucent appearance and helps to prevent additional sunlight and heat from entering the room. There are various color choices available in this film such as pink, light gray, dark gray, tea gold, light blue, off-white. It is also work as a LCD projector film. Generally, it comes in two type one is self adhesive and another is non-adhesive. We sell both, but in second choice an optically clear glue has to be applied to stick it on a glass. There is also a very thin protective covering over a film.

Techinstro has been the leading suppliers and manufacturer of the switchable film in India for many years, and maintain their lead amongst the competition by providing the most efficient, effective and affordable smart film technology.
