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.

Value proposition
Arguments for medical device manufacturers selling to hospitals and health systems:
- Proven clinical efficacy: medical literature documents 30 to 50% faster healing with advanced dressings compared to conventional gauze — relevant in chronic ulcers (pressure, vascular, diabetic foot) where healing time is a critical metric
- Total treatment cost: despite 5 to 10 times higher unit price than gauze, PU dressing allows change intervals of 3 to 7 days instead of daily changes — total cost per treatment episode frequently lower
- Patient quality of life: reduction of pain at changes (dressing does not adhere to wound), reduction of number of changes, optimal moist healing environment — factors relevant in medical decisions and patient satisfaction
- Secondary infection reduction: versions with antimicrobial silver reduce infection in contaminated or high-risk wounds — direct impact on CLABSI (central line associated bloodstream infections) and other hospital-related infections
- Compatibility with advanced therapies: foam dressings are the base for combined therapies (NPWT — negative pressure wound therapy, for example) that generate additional revenue in the treatment cycle
- Population aging and diabetes: global demographic trend ensures sustained growth in demand for advanced wound care products — market resilient to economic cycles
