Thermochromic ink is a specialty ink that can change color reversibly or irreversibly in response to temperature changes. When the temperature reaches or exceeds a specific threshold, the ink's color changes, providing an intuitive temperature indication.
Sterilization indicator ink is a chemical-indicating ink that is sensitive to specific sterilization conditions (e.g., high temperature, steam, ethylene oxide). After the sterilization process, the ink undergoes a permanent color change, visually confirming that the item has been sterilized.
Used for food, medicine, and cold chain logistics to visually indicate temperature changes.
Creates fun interactive effects or indicates if the product is at its optimal use temperature.
Used for sterile packaging to indicate successful sterilization, ensuring patient safety.
Ensures canned goods and ready-to-eat meals have undergone proper sterilization.
The core of thermochromic ink is microencapsulated leuco dyes. When the temperature rises to a set threshold, the substance inside the capsules undergoes a reversible structural change, causing it to change from colored to colorless (or vice versa). When the temperature drops, the color returns. This unique chemical reaction allows it to respond precisely to temperature changes.
No. Sterilization indicator inks are designed for specific methods, such as steam sterilization, ethylene oxide (EO) sterilization, or radiation sterilization. Each ink formula is precisely formulated to respond to specific conditions of temperature, humidity, and gas concentration. When choosing, you must ensure the ink type perfectly matches your sterilization method for accurate and reliable indication.
