HuiZhou StarColor Water Based Ink

【Product Overview】 This hydrogen peroxide plasma (VHP) sterilization indicator ink is a high-end product developed for modern hospitals and manufacturers of precision medical devices. It reacts sensitively to hydrogen peroxide vapor concentration and exposure time. After undergoing a low-temperature plasma sterilization cycle, the ink color undergoes a complete and irreversible change, ensuring the sterilization status of every high-value medical supply is clearly visible. 【Main Application Scenarios】 Precision Instrument Packaging: Compatible with Tyvek roll bags and special medical composite film packaging. Monitoring Consumables: Manufacturing VHP sterilization indicator cards, indicator tapes, and self-sealing bags. 【Core Technological Advantages】 Extremely High Color Change Stability: Specifically designed for the highly oxidizing environment of hydrogen peroxide, ensuring that the color remains vibrant and stable during long-term storage, without fading or reverting. Instantaneous Response Sensitivity: Precisely captures key parameters of the sterilization cycle, changing color instantly upon reaching specified conditions, providing safety assurance for expensive precision instruments. Tyvek Perfect Adhesion: Optimized for Tyvek substrates, the ink dries quickly, does not shed powder, and has excellent scratch resistance, meeting the stringent requirements of sterile barrier systems. Lead-Free, Non-Toxic, and Environmentally Friendly: Uses raw materials that meet global medical regulatory requirements, is completely free of heavy metals, and does not produce toxic substances after sterilization. Precise Color-Changing Scheme: Provides internationally mainstream color-changing paths (e.g., red to yellow, purple to pink, etc.), with extremely high visual contrast. [Technical Parameter Reference] Sterilization Media: Hydrogen peroxide vapor/plasma. Color-Changing Sensitivity: Meets international ISO 11140-1 standard. Printing Method: Flexo printing. Minimum Order Packaging: Offers premium 1kg/bottle packaging for convenient testing in precision medical factories.
