The outermost layer is breathable, bacteria and virus repellent and waterproof made of a polyurethane film that protects the wound from external contamination.

When exudates are absorbed, a soft gel forms in the foam matrix, allowing the dressing to be easily removed.

The hydrocolloid layer forms a gel when absorbing the wound exudates, which ensures a moist wound environment that supports granulation and epithelialization. The gel formation prevents the dressing from adhering to the wound, so the dressing can be removed from the epithelial tissue without causing pain and damaging the granulation.
