Wound care foam dressings
What it is
Polyurethane foam dressings are medical devices used in the treatment of chronic wounds (pressure ulcers, vascular ulcers, diabetic foot ulcers) and acute wounds (post-surgical, burns). The foam is specifically formulated for medical applications — hydrophilic (absorbs wound exudate), biocompatible, soft-textured, with specific moisture management properties.
Wound care PU foam is different from conventional flexible foams. It is specially formulated to:
- Absorb exudate keeping the wound bed in optimal moist healing environment
- Not adhere to the wound (avoiding pain at dressing change)
- Maintain integrity when saturated (not disintegrate)
- Be biocompatible and non-cytotoxic
- Allow controlled gas exchange
Advanced products include dressings with silver (antibacterial), with activated carbon (odor control), combined with TPU film (impermeable yet breathable external barrier), with specific adhesives for sensitive skin, with saturation indicators.
Why it matters
Chronic wounds are a medical problem of massive global scale. Tens of millions of patients live with chronic wounds worldwide, with treatment costs of hundreds of billions of dollars annually. Advanced dressings (such as PU foam) demonstrate faster healing and lower total cost compared to simple gauzes.
For health systems and hospitals, correct use of advanced dressings reduces hospitalization time, number of changes, secondary infections and patient pain. PU foam dressing is one of the most cost-effective products in the wound treatment cycle — although more expensive per unit than gauze, it has significantly superior clinical impact.
For medical device manufacturers, wound care with PU is a high value-added segment, margins superior to commodity products, and sustained growth driven by demographics (global aging, increase in diabetes).
