Abstract
A conformable adhesive article for use as a sterile medical dressing is described. The article includes a breathable polymeric matrix, a plurality of phases, and an adhesive composition positioned on the polymeric matrix. The plurality of phases preferably provide reinforcement and stiffness to the article. The article permits transport of moisture across the breathable polymeric matrix, preferably at an Inverted water moisture vapor transmission rate of at least 300 g/m2/24 hours.
