Thermochromic masterbatch (thermal color changing masterbatch) is a functional additive that changes color reversibly or irreversibly when exposed to specific temperatures.
Our thermochromic masterbatch offers activation temperatures from -15°C to 70°C, covering low-temperature (food/cold chain), room-temperature (promotional), and high-temperature (industrial) applications. All formulations are customizable — you specify the activation temperature, base color, changed color, carrier resin (PE/PP/ABS/PVC), and dosage rate.
Key advantages:
Excellent dispersion — no spotting or streaking
High color strength — vivid before/after contrast
RoHS & REACH compliant — safe for food contact (FDA-grade available)
Custom color matching — Pantone numbers accepted
Explore our complete thermochromic masterbatch series, featuring activation temperatures from 0°C to 70°C. Available in both reversible and irreversible color-change types to suit diverse applications. Carrier resin options include PE-based, PP-based, and EVA-based formulations. All products are RoHS and REACH compliant, with custom color matching and temperature ranges available upon request.
Choose the right activation temperature for your application. Our thermochromic masterbatch covers low-temperature (cold chain), medium-temperature (promotional/consumer), and high-temperature (industrial) scenarios.
Choose between reversible (repeatable color change) and irreversible (one-time indication) based on your application needs.
Choose the right carrier resin for your processing method. All formulations offer excellent dispersion and color strength.We have a variety of carriers such as EVA, PE, PVC, etc.
We offer fully customizable thermochromic masterbatch. Specify your requirements in the table below, and our technical team will formulate a solution for you.
| Parameter | Customization Options | Notes |
|---|---|---|
| Activation Temperature | 0°C to 70°C 0 | Specify exact trigger temperature (e.g., 25°C). Tolerance: ±5-8°C. |
| Base Color | Black, White, Red, Blue, Green, Yellow, Purple | Original color before activation. |
| Changed Color | Transparent (colorless), Red, Blue, Green, Yellow, Purple, Custom | Most customers choose transparent (colorless) after activation. |
| Carrier Resin | PE-based, PVC-based, EVA-based | Match your base material for optimal dispersion. |
| Reversible / Irreversible | Reversible (repeatable), Irreversible (one-time change) | Reversible: >5,000 cycles. Irreversible: permanent indication. |
| Recommended Dosage | 15% – 30% (adjustable) | Depends on desired color strength and carrier resin. |
| Particle Size | 2-4 mm (standard), Custom size available | Smaller particles = better dispersion but higher cost. |
| Processing Temperature | 120°C – 280°C (depends on carrier) | Ensure masterbatch withstands your processing temperature. |
| Certifications | RoHS, REACH, FDA (food contact), None | FDA-grade available for food packaging applications. |
| Packaging | 25kg/bag (standard), 5kg/bag, Vacuum packaging | Vacuum packaging extends shelf life (recommended for long storage). |
Thermochromic masterbatch adds visual temperature indication to plastic products, enhancing safety, interactivity, and functionality. Below are common applications across industries.
Thermochromic masterbatch is widely used in baby products to prevent burns. Our FDA-grade, food-contact safe formulations change color when temperature exceeds 40°C, warning caregivers.
Thermochromic masterbatch adds interactivity to toys. Popular in mood-changing stuffed animals and color-shifting action figures. Reversible type (>5,000 cycles). Non-toxic, EN71 & ASTM F963 compliant.
Novelty drinkware with thermochromic masterbatch changes color at 15°C, indicating water temperature change. This temperature indication enhances user experience. Reversible type standard. FDA-grade
