Thermochromic is a fascinating technological innovation that has revolutionised how we perceive colour. This phenomenon involves a substance that changes colour with temperature variations. The discovery of thermochromism can be traced back to the early 19th century when the French chemist Louis Jacques Thnard first observed the colour change of cobalt chloride upon exposure to heat. Thnard’s discovery sparked a wave of scientific interest in the field of thermochromism, leading to the development of modern-day thermochromic materials used in a wide range of applications, from mood rings to temperature-sensitive packaging and intelligent textiles. The unique properties of thermochromic materials have made them a popular choice for designers and innovators looking to create products that respond to changes in temperature, making them both practical and aesthetically pleasing.
PRODUCT INFORMATION
COLOUR CHANGING: SFXC offers a range of thermochromic film sheets which change from colour to translucent when exposed to temperatures above the activation temperature. The unique property is due to the pigments used in the film, which undergo a reaction that alters their molecular structure. These sheets are easy to use and are made with high-quality materials. They’re a versatile and creative way to add an element of surprise and interactivity to your designs, whether you’re creating product packaging or art projects.
TEMPERATURE ACTIVATED: This smart material becomes translucent or colourless at your chosen activation temperature.
The 15C (59F) activation temperature is perfect for chill and reveal applications, such as using it on an ice-cold surface. This is translucent above 15C and becomes black or a colour, whichever you have chosen when chilled below 15c.
28C for touch-and-reveal applications where warm hands (over 28C or 82F) are present, the 28C (82F) activation temperature is ideal. These sheets are black or a colour, whichever you have chosen, until the temperature reaches 28C, then they become translucent. Please note that the best “opacity” comes from the dark sheets, black, dark green and blue.
The lighter sheets offer no real opacity, in the way of covering the layer below, and the layer below can easily be seen through the sheet, although the sheets do change appearance at 28C, so they still give an effect in Thermochromism.
For HOT & REVEAL applications 45C – And if you’re looking for a heat and reveal application, the 45C (113F) activation temperatu
