Thermal Insulation PDLC Film pdlc film diy
ESWITCH Thermal Insulation PDLC Film DIY Structure And Principle
When the thermal insulation PDLC film is power on, it can keep the transparency of normal PDLC film, when it is power off, appears mysterious and noble gray black. It not only has the switchable characteristics of the excellent performance of normal PDLC film, but also has very good Thermal insulation effect.The pdlc glass film is the best choice for energy-saving design of building.
Features:
a.Noble gray black color, elegant and versatile.
b.High UV blocking rate: ＞95%（power off status）.
High infrared blocking rate ＞75% （power off status）.
c.Big Visible Angle.
d.Energy saving and low carbon environmental protection.
Through reflecting, transmitting and absorbing, to cut off infrared, visible light and ultraviolet light to balance thermal insulation effect and sight clarity.
Solar insulation rate (total insulation rate) = 3% * UV blocking rate + 44% visible light blocking rate + 53% infrared blocking rate

Packaging Protection
ESWITHC PDLC Film is attached with protective film on double-sides. Customers need to remove the protective film before using the film product.
Packing
a.The pdlc film diy can be packaged in roll, roll the product on a 6-inch paper core and wrapped in cushioning material, use the carton packaging on the outside.
b.Identification: A product label is attached to the outside of the carton box to indicate the product name, model number, batch number, quantity, date, etc.
Storage Method
The film should be stored in a warehouse that is ventilated, dry, temperature -15 ° CC ~ 50 ° C, and relatively low temperature 85% RH, away from heat sources. Do not touch acid and alkali gases and liquids during storage.
