STF (Switchable Transparent Film) is also known as PDLC (Polymer Dispersed Liquid Crystal) film, electronic dimming film, electronic curtain, etc. It is based on film technology. The rod-shaped polymer liquid crystalls mixing with prepolymer stick to transparent conductive base material, so that it simultaneously possesses charateristics of liquild and crystal. When powering off, polymer comes to the atomization of disorder. With polymer powering on, it is orderly arranged along with the direction of the electric field, which enables the film to have transmittance of the light. By controling the electric switch, It can be converted between transparent and opaque state. |

The film is composed of PET film,ITO film,polymer and liquid crystal molecules. When the film is under off state, the randomly aligned liquid crystal molecules stay along on the walls of capsule, the reflection of liquid crystal molecules and polymer makes light disperses then it is opaque. While electricity supplied, these molecules arrange themselves in a specific direction then parallel light can pass through the film makes it transparent.

FAQ:
1. How does Smart Film work?
In “Off State” when no electrical power is applied on the smart film the light is absorbed
or scattered and the film looks dark gray or white.
In “On State” the light is transmitted and the film looks transparent.
2. What is the product lead time?
Lead time for PDLC Film Products is 5-7 days after received payment.
3. What is the size of your package?
1 roll / 60 square meter 1* box L146*W38*H38CM
4. What are your shipment terms?
We deliver it by air/express transportation.
Customer clear custom, release and deliver to final destination.
5. Is there a MOQ (Minimum of Quantity)?
1 square meter
6. What is the expected life of your products?
Life expectancy is approximately 8-10 years or switch >2000000times.

Company History:
Main Fields:
As a new material field, functional films are also one of the top ten key fields of Made in China 2025,
and the awareness in the market is increasing. Nowadays, functional films are not only used in the
construction field, special packaging, tape, label, automobile, electronics and other industries,
but also in the fields of film filtration, air permeable film, graphene heating film, insulation film,
Anti-UV film, biodegradable materials etc..
UPASS, as a leading domestic deep cultivator of polymer functional films, has also entered a stage
of rapid development. We believe that UPASS will enter more application fields of polymer films in
near future.
