ABSTRACT:
By incorporating chemical reinforcing additives into a polyurethane resin base, a unique, reinforced moisture vapor permeable membrane is achieved which comprises a substantially increased modulus of elasticity, rendering the membrane easier to handle and employ. In the preferred embodiment, the polyurethane resin base comprises a blend of polyurethane resins and the two chemical reinforcing additives comprise a non-urethane copolymer resin and silica. Furthermore, a moisture vapor permeable, pressure-sensitive adhesive is applied to one surface of the membrane, thereby attaining a wound dressing which is easy to handle and employ for various surgical procedures.
