PermaFoam Foam Dressings

PermaFoam is a line of hydropolymer foam dressings from Hartmann, developed to manage moderately to heavily exuding wounds while keeping the wound bed in a balanced, moist environment. Clinicians reach for foam dressings when they need dependable absorption without sacrificing patient comfort, and the PermaFoam range is built around exactly that priority — soaking up excess exudate, locking it away from the wound surface, and cushioning the area against pressure and friction.

The structure of these dressings is what sets them apart. A hydrophilic polyurethane foam core draws fluid vertically into the dressing rather than letting it spread laterally, which helps protect the surrounding skin from maceration. That vertical absorption, combined with a high fluid-retention capacity, is why PermaFoam is frequently chosen for chronic wounds such as venous leg ulcers, pressure ulcers, and diabetic foot wounds, as well as for donor sites and other exuding secondary wounds.

Buyers often ask how long a foam dressing can stay in place. Because PermaFoam holds a large volume of exudate and maintains a moist healing environment, wear time can extend for several days depending on drainage levels — reducing dressing changes, disturbance to the wound, and overall supply costs. Contoured and cavity versions within the range address anatomically difficult areas like the heel and sacrum, where standard flat dressings tend to lift or bunch.

PermaFoam works well as part of a layered protocol. Pair it with an appropriate antimicrobial when infection risk is a concern, or explore adhesive-bordered options for wounds that need secure fixation without extra taping.
