These are reversible thermosensitive foils in liquid crystal technology.
Such foils are coated with special, microencapsulated liquid-crystals reacting by colour changes to temperature variations within their specified range of "temperature versus colour" play. These Polyester material based foils are available with or without adhesive backing.
Our LC-Foils are mostly manufactured to customers specific needs for size, temperature range and other parameters.
Below and above its specific colour play the LC-foil is black. Starting the temperature move from below temperature sensitive window towards and through the visible part of the colour play, the colours will go through a sequence of black -> reddish -> yellow ->green to -> final dark-blue (black) sequence. Any additional temperature increases will not cause any additional colour variations. The colour play reverses when temperatures are passed in opposite direction. LC-Thermofoils are defined by the temperature level at which the colours start to play and the temperature band (width) within the colours do play from low end black to high end black.

LC-Thermofoils can be printed with various staged temperature levels and become LC-Thermostrips, see image to the left.
