Thermochromic Pigments
Smart pigments that reversibly change color in response to temperature variations.
Principle
Based on microencapsulated systems containing color formers, developers, and solvents. Color changes occur when thermal energy triggers molecular rearrangement.
Chemical Properties
Reversible color transition at specific temperatures. Activation range: -15°C to 65°C (customizable). Repeated cycle stability (>10,000 cycles).
Manufacturing Process
Advanced microencapsulation technology protects the thermochromic compounds in polymer shells, ensuring durability and processing stability.
Application Methods
Dosage: 2-10% for visible color change. Process below 230°C to avoid microcapsule damage. Suitable for injection molding, extrusion, and coating applications.
Thermochromic Pigments Products
