What is silicone?

Silicones are inert synthetic polymers made up long chains of siloxanes. These contain silicon and other elements. Silicones have many industrial uses and can vary in form from oil, to rubber and hard resins.

Why use silicone for medical dressings?

The following specific properties make silicone useful for medical dressings:

How do silicone dressings work?

Soft silicone is a particular family of solid silicone that is soft and “tacky”. The tack of soft silicone means it can form a seal around a wound by creating multiple points of adherent skin contact. This is particularly useful to patients with fragile skin (eg epidermolysis bullosa and elderly patients).

Silicone has a stable and immediate adhesive profile unlike acrylic adhesives, which progressively become more adhesive with duration of application. The “tack” of silicone dressings is retained, allowing the dressing to be reapplied multiple times without loss of adhesion.

The hydrophobic property of silicone prevents adherence to moist wound bases, so it is relatively atraumatic.

Soft silicone dressings are designed to:

  1. Be comfortable
  2. Reduce pain and trauma of epidermal stripping during dressing changes
  3. Protect skin around the wound from contact with exudate
  4. Not adhere to moist surfaces
  5. Not leave a residue following removal
