Temperature-Activated Magic

Choose the activation temperature that best suits your project:

  • 15°C: Ideal for "chill and reveal" applications, where the colour appears when cold.
  • 28°C: Perfect for "touch and reveal" applications, activated by the warmth of a hand.
  • 45°C: Suited for "heat and reveal" applications, where the colour appears when hot.

We also offer customised activation temperatures to meet your precise requirements (minimum order quantity applies).

A Smart Material for Innovative Designs

Thermochromic film is a cutting-edge smart material that dynamically changes its properties in response to temperature variations. This innovative technology opens up a world of possibilities for creative and engaging designs.
