Antimicrobial medical grade TPU cable material is a special thermoplastic polyurethane material that provides a non-specific sterilization mechanism by adding antimicrobial agents, effectively inhibiting bacterial growth and reducing the risk of infection associated with medical devices. The antimicrobial properties of this material are particularly important for hospitals and medical environments because they can reduce the growth of bacteria and fungi on the surface of equipment.
Good biocompatibility: good compatibility with human tissue, non-toxic, non-allergenic, suitable for medical devices.
Excellent physical and mechanical properties: high strength, high toughness and wear resistance, meeting the durability requirements of medical equipment in long-term use.
Antibacterial effect: by adding nano-silver antimicrobial agents, etc., it has excellent antibacterial effects on a variety of bacteria, molds, yeasts and algae.
High temperature and aging resistance: It can still maintain good performance under high temperature conditions and is suitable for medical environments that require disinfection.
No impact on transparency and physical properties: The addition of antimicrobial agents does not affect the transparency and basic physical properties of the material.
When preparing antibacterial medical-grade TPU cable materials, antibacterial agents can be added to TPU materials by melt blending. Studies have shown that different amounts of antibacterial agents have different effects on the physical properties, thermodynamic properties and antibacterial activity of the materials. For example, the addition of nano-silver-loaded antibacterial agents can improve the tensile strength and elongation at break of the material, while enhancing its antibacterial activity. When the added mass fraction is 1.5%, the antibacterial activity values of the material against Escherichia coli, Staphylococcus aureus and Candida albicans reach 5.6, 5.2 and 4.1 respectively, showing good antibacterial effect.
