InterSil Wound Contact Layer

InterSil Wound Contact Layer

InterSil is a thin, perforated, low adherence, silicone wound contact layer dressing consisting of a nonwoven matrix, coated with a soft silicone layer on both sides. The silicone wound contact layer is protected by a clear embossed LDPE liner on both sides. InterSil forms a protective barrier for granulation tissue to grow undisturbed by frequent changes of the outer absorbent dressing being used. This product allows exudate to pass through it, preventing wound maceration without hindering the function of the absorbent dressing.

Typical Application

Designed for the treatment of postoperative wounds, first- and second-degree burns, partial to full thickness wounds, stage I-IV pressure ulcers, and arterial and venous leg ulcers.
