The challenge

Typical wound dressings are an assembly of composite components, combining different types of materials: a backing film for comfort and integrity, an hydrophilic absorbent for managing exudates and an adhesive layer that is designed to guarantee soft adhesion to skin, while remaining elastic and permeable. Soft silicone adhesives combined with polyurethane films are materials of choice for this adhesive layer because they are highly breathable, biocompatible and flexible.
