Thermochromic Pigment Powder –  Black to Red

All of our Thermochromic pigments change at 31 degrees Celsius and revert back to the original colour below this temperature

Thermochromic pigments are a type of colour-changing pigment that respond to changes in temperature. They are designed to change colour or become transparent when exposed to heat, and then revert back to their original colour as they cool down.

Thermochromic pigments are made up of microcapsules or microspheres containing a colourant that is sensitive to temperature. These microcapsules are typically mixed into paints, inks, or coatings, allowing them to be applied to various surfaces.

The pigments are engineered to undergo a reversible colour change at a specific temperature range, known as the activation or transition temperature. Below this temperature, the pigment exhibits one colour, and as the temperature rises above the activation temperature, it transitions to a different colour or becomes transparent. Once the temperature drops back below the activation temperature, the pigment reverts back to its original colour.

The colour change of thermochromic pigments is based on the principles of thermochromism, which involves the rearrangement of molecules within the pigment’s structure in response to temperature variations. This rearrangement affects the absorption and reflection of light, resulting in a noticeable change in colour.

Thermochromic pigments have various applications. They are commonly used in temperature-sensitive packaging, such as labels on beverage cans or baby bottles, to indicate if a product is too hot to touch or consume. They are also utilized in novelty items, toys, clothing, and mood-changing products where the colour change adds an interactive and dynamic element.

It is important to note that thermochromic pigments can have specific temperature activation ranges and durability limitations. Extreme temperatures, prolonged exposure to sunlight, or certain chemical interactions may affect their performance and lifespan. Therefore, careful consideration should be given to the specific requirements and application guidelines provided by the manufacturer when working with thermochromic pigments.
