DIGI-TEMP Liquid Crystal Sheets
Ready to use 12” x 12” size polyester sheets coated with liquid crystal that change color as temperature increases, the color of the sheets changes from black to red, red to green, green to blue, and finally to black again These sheets exhibit the characteristics of liquid crystal thermometers and are suitable for research, education and non- destructive testing.

Liquid Crystal Film (Vinyl Flex)
Ready to use vinyl material with a glossy finish and coated with liquid crystal. This is a finished material supplied in rolls and slit to size or sheeted, that can be cut to size and used to create a touch sensitive color changing graphic. This is a bright material utilizing unsealed liquid crystal designed for decorative applications.

Liquid Crystal Formulations
Thermochromic Liquid Crystals are optically active mixtures of organic chemicals that can be highly temperature sensitive and change to many colors.  LC s start black below their temperature range go through the colors of a rainbow and then black again above the temperature range.  Liquid Crystal is reversible so they can be used over and over again
