Polyurethane Foam Dressing
Porous polyurethane foam with semi-permeable film backing — manages exudate through two mechanisms: absorption into open-cell foam structure and moisture vapor transmission (MVT) through the backing film. Available in non-adhesive, adhesive bordered (acrylic), and silicone bordered formats. EN 13726:2023 tested.

How It Works
4-Layer Construction & Dual Performance Mechanism
1
Wound contact surface
Heat-treated PU foam surface or soft silicone contact layer (silicone-contact variants). Non-adherent to the moist wound bed due to PU foam's surface properties — allows atraumatic removal without disrupting wound tissue.
2
Absorbent foam core
Open-cell polyurethane foam — absorbs exudate by capillary action into the foam cell structure. Does not liquefy or leave particulate matter in wounds. Provides cushioning to protect the wound from mechanical impact.
3
Semi-permeable backing film
Polyurethane film — waterproof outer surface blocks liquid water and bacteria from external environment. Allows water vapor to evaporate through the film (MVTR), contributing significantly to total fluid handling capacity. Published research (Lee et al., 2016) found MVTR varying 2,000–20,000 g/m²/24h across commercial foam dressings — always request this value.
4
Adhesive border (bordered types)
Acrylic adhesive (standard bordered) or soft silicone adhesive (silicone bordered) applied to a film extension beyond the foam pad. Secures the dressing to surrounding skin; no secondary tape or bandage required for bordered formats.
MVTR is the key performance differentiator — always request the measured value
EN 13726:2023 specifies how to measure MVTR but sets no minimum pass/fail thresholds yet. Two foam dressings with similar absorption capacity can have dramatically different total fluid management due to backing film MVTR. Request the actual EN 13726 test report with numeric MVTR (g/m²/24h) — not just a compliance statement. See our Foam Dressing Specifications Guide for full explanation.
Types Available
Choose Your Format
No secondary dressing needed
Adhesive Bordered (Acrylic)
Foam pad with acrylic adhesive perimeter border. Self-adhesive to surrounding skin. No secondary securing dressing required. Most commonly procured bordered format for ward and outpatient use. Available in standard rectangular, oval, heel, and sacral shapes.
Best for: Post-operative wounds, pressure injuries, general ward use, outpatient settings.
Most atraumatic removal
Silicone Bordered
Same foam core and film backing as acrylic bordered, but with soft silicone adhesive on the border. Allows repositioning; less trauma on removal — preferred for fragile peri-wound skin, elderly patients, or wounds requiring frequent dressing changes.
Best for: Elderly patients, fragile skin, pressure injuries on bony prominences, repeated dressing changes.
Under compression bandaging
Non-Adhesive (Flat)
No adhesive layer — secured by secondary bandage, tape, or tubular net. No adhesive border creating pressure differential under compression. Preferred format for venous leg ulcer management under compression systems.
Best for: Leg ulcers under compression, fragile peri-wound skin, cost-sensitive ward procurement.
Deep / cavity wounds
Cavity / Filler Foam
Rope, ribbon, or amorphous format designed to fill wound cavities and undermining. Expands with fluid absorption to maintain contact with wound walls. Must be removed before full gelling — follow manufacturer wear time guidance.
Best for: Post-surgical wound dehiscence, pilonidal sinus, deep wounds with undermining.

| MVTR (backing film) | Request actual measured value (g/m²/24h) from supplier EN 13726 test report | Published range across commercial products: 2,000–20,000 g/m²/24h (Lee et al., 2016). Key performance differentiator |
| Adhesive type (bordered) | Acrylic (standard) or soft silicone — specify at order | Silicone = repositionable, more atraumatic on fragile skin |
| Formats available | Non-adhesive flat · Adhesive bordered (acrylic) · Silicone bordered · Cavity/filler | Specify format; "foam dressing" alone is not sufficient |
| Standard sizes | 10×10 cm / 15×15 cm / anatomical (heel, sacral) — specify by application | Custom sizes available |
| Under compression | Non-adhesive format only — adhesive bordered not recommended under compression | Adhesive border creates pressure differential under compression bandaging |
