Hydrophilic PP Nonwoven/Waterproof PE Composite for Surgical Fenestration Drapes
This medical composite material consists of hydrophilically treated polypropylene (PP) nonwoven laminated to a waterproof polyethylene (PE) film, engineered for optimal fluid management in surgical drapes.
The PP nonwoven layer undergoes a permanent hydrophilic treatment, enabling rapid absorption and distribution of bodily fluids (absorption rate: ≥300% self-weight), while the PE film layer acts as an impermeable barrier (hydrostatic pressure resistance: >50cmH2O) to prevent liquid strike-through. With a grammage range of 40-75gsm, the composite balances absorption capacity and drape flexibility.
The material's blue hue enhances visibility against surgical fields, reducing procedural errors. The PP-PE bonding utilizes medical-grade adhesives, ensuring delamination strength >4N/cm even under wet conditions. Certified to ISO 13485 and AAMI PB70 Level 3 standards, it is compatible with gamma/Ethylene Oxide sterilization.
Key applications include:
Fenestration drapes: Absorbs exudates at the incision site while blocking lateral leakage.
Fluid-control surgical gowns: Combines breathability (MVTR: 800-1200g/m²/24h) with barrier integrity.
Wound dressing backing: PE film prevents exudate contamination of external surfaces.
