TPU Coated 70D Nylon Fabric for Anti-Decubitus Air Mattresses

Our TPU Coated 70D Nylon Fabric is a premium composite material developed for the demanding application of alternating pressure air mattresses and static air overlays. The fabric utilizes a tightly woven 70D nylon base, chosen for its exceptional tensile strength, tear resistance, and critically, its excellent dimensional stability with minimal elongation under pressure. This stable substrate is precision-coated on one side with a uniform layer of medical-grade Thermoplastic Polyurethane (TPU), creating a flawless, impermeable, and flexible airtight barrier. In mattress systems, this barrier is vital for maintaining independent, pressure-stable air cells that can reliably inflate, deflate, and cycle to redistribute pressure away from a patient’s body. The fabric’s robustness ensures it can withstand the constant mechanical stress of weight-bearing, repeated pressure cycling, and frequent cleaning in clinical environments. Its reliable performance makes it an ideal material for constructing the core inflatable chambers in both dynamic alternating pressure mattresses and static air flotation mattresses used in hospitals, long-term care facilities, and home care settings.

Key Features & Benefits

• Superior Airtightness & Pressure Stability:​ The continuous medical-grade TPU coating ensures a perfect, leak-proof seal for each individual air cell, maintaining consistent and precise air pressure for effective pressure redistribution and patient comfort.
• High Durability & Puncture Resistance:​ The robust 70D nylon base combined with the TPU coating provides excellent resistance to punctures, tears, and abrasion from prolonged patient contact, bed frames, and sheets, ensuring long service life.
• Excellent Dimensional Stability & Low Stretch:​ Minimal elongation under load prevents air cells from over-expanding or deforming, which is critical for maintaining proper cell height, pressure distribution, and mattress functionality.
• Withstands Constant Pressure Cycling:​ Engineered to endure thousands of inflation/deflation cycles in alternating pressure systems without material fatigue or failure, ensuring reliable long-term operation.
• Chemical & Fluid Resistant:​ The coated surface resists stains from bodily fluids and is compatible with common hospital disinfectants and cleaning agents, facilitating infection control and maintenance.
• Flexible & Conformable:​ Remains pliable to allow the mattress to comfortably contour to the patient’s body, enhancing pressure relief and comfort without creating pressure points.
• Strong, Reliable Weldability:​ Excellent for high-frequency (HF) welding, enabling the creation of strong, airtight, and durable seams that are essential for the integrity of complex multi-cell mattress designs.
