Thermochromic Pigments

Our thermochromic pigments feature the following characteristics:

• Color Change Principle: Colored at low temperature and colorless at high temperature, reversible color changes

• Temperature Range: -5°C ~ 70°C

• Color Range: Capable of achieving various color changes

• Basic Colors: 15 base colors available, all colors can be mixed and matched, also compatible with other pigments

• Customization: Color matching according to customer requirements, achieving combinations between thermochromic and regular colors

Thermochromic Powder Usage:

For injection molding, extrusion processing, casting, compression molding, or curing, use 0.5%-1.0% thermochromic pigment relative to the plastic content. Thoroughly mix the thermochromic pigment with plastic particles (a small amount of white oil can be used during mixing). When combining regular pigments with thermochromic pigments, use regular pigments (or dyes) at 0.5-2.5% of the thermochromic pigment amount.

Processing temperature should be kept below 200°C, not exceeding 220°C, and minimize material heating time. (High temperature and prolonged heating will damage the color-changing properties).

Thermochromic Ink Usage:

1. Drying Methods: (Air-dry, bake-dry, UV curing), can be diluted with appropriate solvents. (Water-based inks are also available, dilutable with water) Recommend white or light-colored backgrounds for better color change contrast. 2. Screen Selection: Choose mesh count between 150-200. 3. Solvents: Can be diluted with appropriate solvents. (Water-based inks are also available, dilutable with water) 4. Storage: Store thermochromic inks in sealed, dry, dark places away from direct sunlight.

1. Substrate selection: Best suited for materials with pH 7-9, plastic substrates with MI value above 25 are preferred, higher MI values result in better color change effects 2. Thermochromic materials are free from harmful substances and comply with food packaging and toy safety standards. 3. Storage: Store thermochromic materials in sealed, dry, dark places away from direct sunlight.
