Product Specification

SPD Smart Film

Suspended Particle Device (SPD) electrochromic technology. Instantly shifts from a dark blue, light-absorbing state to completely transparent, offering ultimate glare control, solar shading, and thermal comfort.

Deep Dark State

When powered off, SPD particles absorb over 98% of visible light, creating a deep blue opaque state for excellent solar shading.

Precise Tint Control

The entire tinting and bleaching process can be precisely controlled by adjusting the 90V AC voltage.

99% UV Blocking

Provides outstanding sun protection by blocking up to 99% of harmful UV rays across all tint states.

Ultra Low Power

Consumes only ~3 W/m², making it a highly energy-efficient solution for large-scale glazing projects.

How SPD Technology Works

SPD works by dispersing millions of suspended particles between two transparent conductive layers. The tint level dynamically responds to applied voltage:

  • Power OFF = Dark Blue (Opaque)The SPD particles remain randomly distributed, absorbing over 98% of visible light. The film appears in a deep dark blue state, heavily reducing solar glare and heat.
  • Power ON = Transparent (Clear)When 90V AC current passes through the conductive layers, the particles instantly align in an orderly manner. This allows light to pass through, switching the film to a highly transparent state (60% transmittance).
