Liquid Crystal Film (Vinyl Flex)
Thermochromic Liquid Crystals are optically active mixtures of organic chemicals that can be temperature sensitive and change colors. Liquid Crystals start black below their temperature range, go through the colors of a rainbow, then rotate back to black, above the temperature range. Liquid Crystal is reversible so they can be used repeatedly.
Liquid Crystal Films are ready to use vinyl material coated with a glossy finish and liquid crystal. The finished material is supplied in rolls and can be slit or sheeted to size, creating a touch-sensitive color changing graphic. Designed for decorative applications, the finished product is a bright material utilizing unsealed liquid crystal.
