Thermochromic powder is a pigment whose color changes caused by chemical structure change caused by heat. Temperature-changing products have the characteristics of changing from colored to colorless when rising to a specific active temperature. They are usually divided into low-temperature discoloration and high-temperature discoloration, and their color changes are usually reversible.

1. Key Features

Reversibility: Most temperature-changing powders will return to their original color after the temperature recovers (irreversible types require special formulation).

Responsive: The color change time is usually completed in a few seconds.

ENVIRONMENTAL FRIENDLY:  Some products meet food contact standards and can be used in tableware or toys.

2. Fields of application

• Consumer goods:

•Temperature-sensitive cups, baby bottles (indicate temperature).

Clothing/shoes and hats (dynamic pattern design).

• Industrial Use:

Board temperature detection label.

Automotive paint (showing overheated areas of the engine).

• Creative design:

Interactive installation of temperature-changing nail polish and artwork.

3. Precautions for use

Durability: Long-term UV exposure may cause fading, and anti-UV agents need to be added.

Processing limitations: Avoid high temperature processes (e.g. injection molding temperatures exceeding 150℃ will destroy microcapsules).

4.  Examples of common types of markets

Low temperature type (22℃ discoloration): Suitable for refrigerated food labels.

High temperature type (above 31℃-45℃): Used in industry, various plastic products, paint ink, equipment monitoring, etc.
