How PolyMem ® Works


PolyMem Provides Continuous Wound Bed Cleansing
The dressing contains a mild, non-toxic, nonionic, tissue friendly cleansing agent that is activated by moisture, drainage, and/or exudate and is gradually released into the wound bed. This reduces interfacial tension between healthy tissue and debris, loosens eschar and necrotic tissue, and supports autolytic debridement - all while keeping the wound bed clean throughout healing.

PolyMem Encourages Wound Comfort and Health
Glycerin (also known as glycerol), a moisturizer contained in the dressing, keeps the dressing from adhering to the wound bed and provides comfort at the wound site. Glycerin also reduces odor, conserves living fat cells, reduces hypergranulation, soothes traumatized tissues, and supports autolytic debridement.

PolyMem Offers Impressive Wound Wicking Power
The polyurethane membrane matrix wicks away up to ten times its weight in exudate. It removes in one piece and will not fragment or leave residue in the wound bed. The superabsorbent starch copolymer in QuadraFoam absorbs and binds the water molecules from the wound fluid, allowing the natural growth factors and nutrients to concentrate in the wound bed.

PolyMem Provides Both a Liquid Barrier and Gas Exchange
The semipermeable thin film backing provides a liquid barrier while allowing gas (O2 and CO2) exchange and maintaining an ideal Moisture Vapor Transmission Rate (MVTR) in order to optimize the appropriate moisture balance for healing the wound. The transparent film backing allows visual inspection of the membrane to determine the need for a dressing change.
