ECTOFOAM dressings are composed of a soft, conformable, microporous, hydrophilic, polyurethane foam with a highly breathable polyurethane film backing. ECTOFOAM is designed to absorb large amounts of exudate. The wound contact layer of foam is hydrophilic, so absorbs exudate. The outer layer is hydrophobic, so fluid can’t leak, but vapour can escape. This creates and maintains a moist wound environment which promotes healing.
