PVC stabilizers are essential for PVC medical products, with calcium-zinc (Ca Zn) stabilizers preferred for their eco-friendly and non-toxic properties. Given PVC medical items’ direct human contact, these attributes are pivotal to ensuring product safety, stability and performance, helping manufacturers meet global medical industry’s stringent safety standards.
TopJoy’s Ca Zn stabilizers address these needs with three key medical-specific functions. First, thermal stability inhibits PVC degradation during high-temperature processing (e.g., extrusion, molding) and sterilization, ensuring material integrity throughout production.
Second, biological safety is paramount—these stabilizers are heavy metal-free and meet medical-grade low migration requirements, preventing harmful substance transfer during use, which aligns with non-negotiable safety demands for human-contact medical applications. They also optimize performance by enhancing processability, efficiency, weather resistance and mechanical properties, extending product service life.
TopJoy provides tailored Ca Zn stabilizer types for different PVC medical products. Liquid variants offer excellent solubility and dispersion, ideal for soft items like infusion tubes/bags, ensuring flexibility, transparency, reducing defects and low-temperature processing. Powder types suit products needing long storage or frequent sterilization (e.g., surgical packaging, syringes), providing long-term stability, low migration and strong resin compatibility. Paste variants excel in transparency, dynamic stability and aging resistance, perfect for high-clarity products like oxygen masks, precision drip tubes and blood bags. For manufacturers, these targeted solutions ensure stable production, high-quality compliant products and enhanced market competitiveness.
