AI Technical Summary
Existing TPU materials have insufficient antibacterial and stain-resistant properties in high-frequency contact scenarios such as medical supplies and sports equipment. In addition, the chemical properties are affected by the additives, and the antibacterial components are prone to migration or failure. It is difficult to meet the dual requirements of high-end application scenarios at the same time, and the preparation process is complicated.
Thermoplastic polyurethane is synthesized by introducing quaternary ammonium salt units and silane-containing chain extenders into polyester polyols, giving it antibacterial and stain-resistant properties. The material surface is not easily stained and can effectively inhibit bacterial growth.
This technology improves the antibacterial and stain-resistant properties of TPU materials, resulting in less surface stains and better bacterial inhibition. It is suitable for applications such as smart wearables, medical devices, sports equipment, and automotive interiors.
