A primary wound dressing made from the calcium salt of alginic acid, which is rich in mannuronic acid

A two-layer dressing comprising a non-adherent, highly absorbent polyurethane foam and a breathable polyurethane film backing. The foam core is designed to absorb and retain exudate, while the outer layer allows moisture vapour transmission away from the dressing.

A three-layer dressing comprising a highly absorbent polyurethane foam core, a breathable polyurethane film and a translucent, breathable polyurethane backing

A two-layer dressing comprising an absorbent hydrocolloid matrix laminated to a highly breathable polyurethane film backing. The hydrocolloid matrix absorbs exudate and forms a cohesive gel, while the breathable polyurethane film backing provides a high rate of moisture vapour transmission.

Comprises an absorbent hydrocolloid matrix, which has a border laminated to a highly breathable polyurethane film backing. The hydrocolloid matrix absorbs exudate and forms a cohesive gel, while the breathable polyurethane film backing provides a high rate of moisture vapour transmission.
