PVC stabilizers are indispensable in the production of PVC medical products.Ca Zn stabilizers are environmentally friendly and non-toxic, play a key role in ensuring their safety, stability, and performance.
Core Functions
Thermal Stability: Inhibits high-temperature degradation of PVC, ensuring material stability during processing and sterilization.
Biological Safety: No heavy metals, meeting medical-grade low migration requirements, suitable for human contact scenarios.
Performance Optimization: Improves material processability, weather resistance and mechanical properties, extending the service life of medical products.
Product Types and Characteristics
Liquid Ca Zn stabilizer: Excellent solubility and dispersion; ideal for soft PVC medical products like infusion tubes and bags, ensuring their flexibility and transparency, reducing defects, and suitable for low-temperature processing.
Powder Ca Zn stabilizer: fits medical products needing long storage or frequent sterilization such as surgical instrument packaging films,injection syringe，ensuring their long-term stability, with low migration and compatibility with various PVC resins.
Paste Ca Zn stabilizer: excellent transparency, dynamic stability, resistance toaging, and good processability, lt is suitable for the processing of high-transparency PVC soft and semi-rigid products, such as oxygen masks, drip tubes and bloodbags.
