Pharma-Foam® Silver is a trilaminate construction made of soft, thick and elastic polyurethane foam sandwiched between an outer most breathable polyurethane film and wound contacting polyethylene net containing silver. The silver net acts as antimicrobial barrier which prevents colonization on the dressing, thus it increases wear time and provides a prophylactic effect against infection especially in case of wounds at high risk of infection.
Polyurethane foam provides a cushioning effect and high absorption capacity up to 14 g/g. This provides dry but moist environment which is in favour of all wound healing stages specially the granulation and the epithelialisation phase, so it accelerates wound healing.
The polyurethane film outermost layer is highly breathable, up to 5000 g/m2/24hr MVTR. This allows evaporation of wound exudates absorbed by foam, thus the total fluid uptake and fluid handling capacity of the dressing in total is increased. It is also bacteria proof, virus proof and waterproof.
The silver net prevents colonization of bacteria over the dressing, so it increases the wear time and decreases frequency of changing the dressing. It provides both hygienic and economic benefits.
