SPD Film-The switchable film with SPD (Suspended Particle Devices) technology represents a revolutionary innovation in the field of light management. This advanced technology enables the dynamic control of light transmission through the application of electrical voltage, offering excellent versatility in various fields.
The SPD film consists of two outer layer of polyester film (PET), coated on the inside surfaces with a transparent conductive layer. A layer of SPD compound is sandwiched betweenthe two PET film supports.The films filter out 99.9% of UV rays from outside. In addition, when combined with specific double-glazing configurations with selective outer glass, they can also reduce the heat of the interior environment. In the OFF state they are blue in colour while in the ON state they are transparent.
Standard film widths: 1200mm, 1500mm.
Standard formats: Rectangular sheets obtained by laser cutting, according to required dimensions.
Cutting and customisation: Possibility of cutting curved shapes, pre-cutting the strip for the electrodes, applying the electrodes to positions requested by the customer from a range of standard combinations.
