Antibacterial Medical Grade TPU Cable Material

Antimicrobial TPU Compounds for Medical Device Cables

This TPU material provides antimicrobial protection against Staphylococcus aureus, Escherichia coli, and Candida albicans. It also resists mold, microorganisms, chemicals, alcohol, acids, alkalis, and hydrolysis. The material is non-hemolytic.

It supports gamma and ETO sterilization. It has low drug adsorption, bonds easily, and maintains high transparency, strength, and flexibility—performing better than PVC. It comes with ISO-10993 biocompatibility test reports and ISO 9001 compliance. The surface has a soft matte finish and meets VW-1 flame-retardant requirements. It is halogen-free, eco-friendly, non-toxic, and compliant with RoHS, REACH, and other standards.

This antimicrobial medical-grade TPU is a specialized thermoplastic polyurethane. By adding antimicrobial agents, it suppresses microbial growth and reduces infection risks linked to medical devices. These features are especially valuable in clinical environments, where equipment surfaces need protection from bacteria and fungi.

Key Characteristics

Biocompatibility

Safe for contact with human tissue. Non-toxic and non-allergenic, suitable for medical devices.

Strong physical performance

High strength, toughness, and wear resistance, meeting long-term durability needs in medical equipment.

Antimicrobial function

Nano-silver and other agents provide strong antibacterial effects against bacteria, mold, yeast, and algae.

Heat and aging resistance

Maintains stable performance in high-temperature disinfection environments.

No major impact on transparency or physical properties

The antimicrobial additives do not affect clarity or core material properties.

Material Preparation

Antimicrobial agents can be added through melt blending. Different additive levels will influence the material’s physical, thermal, and antibacterial performance.

Nano-silver agents can increase tensile strength and elongation while improving antimicrobial activity. When added at 1.5% by mass, the material shows antibacterial activity values of 5.6 against E. coli, 5.2 against Staphylococcus aureus, and 4.1 against Candida albicans, indicating strong antimicrobial performance.
