TPU Coated Velvet Fabric for Inflatable Medical Boots

Our TPU Coated Velvet Fabric is a sophisticated composite material developed for critical medical applications. The substrate consists of a high-density polyester velvet, offering a plush and low-irritation surface for direct patient contact. The backside is precision-coated with a layer of medical-grade Thermoplastic Polyurethane (TPU) through an advanced coating process. This construction ensures exceptional air retention, forming a robust yet flexible air chamber when sealed. The fabric is designed to withstand repeated inflation/deflation cycles, maintaining its structural integrity and comfort throughout the rehabilitation period. It is the ideal core material for constructing the inflatable bladder system within pneumatic walking boots, fracture braces, and sequential compression devices.

Key Features & Benefits

• Dual Comfort:​ Velvet face provides a soft, skin-friendly interface that reduces friction and pressure points, enhancing patient compliance during extended wear.
• Superior Airtightness:​ The continuous medical-grade TPU coating forms a flawless barrier, ensuring excellent air retention for consistent and reliable compression therapy.
• High Durability & Puncture Resistance:​ Exceptional tensile strength and resistance to abrasion and puncture, guaranteeing long-term performance and reducing failure risk.
• Excellent Flexibility & Drape:​ Remains supple across a wide temperature range, allowing the boot to conform comfortably to limb contours without restricting movement.
• Strong Welding/Sealing Performance:​ The TPU layer enables clean, high-strength high-frequency (HF) or thermal welding, creating durable seams that are crucial for air bladder integrity.
• Easy to Clean & Hygienic:​ The smooth, non-porous TPU surface resists fluid penetration and allows for easy wiping and disinfection between uses.
• Lightweight:​ Contributes to the overall light weight of the medical device, improving patient comfort and mobility.
