TPU-beschichtetes 70D-Nylon-Gewebe für chirurgische Tourniquets

Our TPU Coated 70D Nylon Fabric is a premium composite material specifically optimized for the demanding environment of surgical tourniquets. The base is a tightly woven 70D nylon substrate, renowned for its outstanding tensile strength, tear resistance, and minimal elongation under pressure. This fabric is precision-coated on one side with a uniform layer of medical-grade Thermoplastic Polyurethane (TPU), creating a flawless, impermeable barrier. The resulting laminate is designed to withstand the high cyclic pressures and rapid inflation/deflation required in surgical and emergency settings. Its high strength-to-weight ratio contributes to a durable yet lightweight cuff, while the low-stretch characteristic ensures precise pressure control and prevents cuff deformation or “ballooning” during use. This fabric is the industry-preferred choice for constructing reliable, safe, and long-lasting inflatable bladders in both single-use and reusable pneumatic tourniquet systems, as well as in other high-pressure medical compression devices.

Hauptmerkmale und Vorteile

• Superior Airtightness & High-Pressure Integrity:​ The continuous TPU coating provides a perfect seal, ensuring reliable air retention and consistent pressure delivery up to high pressures, which is critical for effective surgical occlusion.
• High Burst Strength & Puncture Resistance:​ The 70D nylon base combined with the TPU coating offers exceptional resistance to internal pressure and external punctures, maximizing patient safety and device reliability.
• Low Stretch & Excellent Dimensional Stability:​ Minimizes elongation under high pressure, preventing uncontrolled cuff expansion (“ballooning”) and allowing for precise, consistent pressure application as per set parameters.
• High Strength-to-Weight Ratio:​ Provides the necessary durability and robustness for a tourniquet cuff while maintaining a lightweight profile, contributing to user comfort and ease of application.
• Abrasion & Tear Resistant:​ Withstands repeated use, handling, and potential contact with surgical tools or skin prep solutions, ensuring longevity, especially in reusable cuff designs.
• Excellent Weldability/Sealability:​ The TPU coating enables strong, hermetic, and clean high-frequency (HF) or thermal welds, crucial for creating durable, leak-proof seams in the air bladder.
• Chemical & Fluid Resistance:​ Resists degradation from common disinfectants, cleaning agents, and bodily fluids, facilitating cleaning and reprocessing for reusable models.
