What is the difference between the black foam and the white foam?
The black foam (polyurethane, or GranuFoam® Dressing) is hydrophobic or water repelling. It is an open pore foam, which allows for exudate to be removed. It is less dense than the white foam (polyvinyl alcohol, or Vers-Foam™ Dressing) and is reticulated, which means all the pores are in communication with each other. This design allows for increased distribution of negative pressure across the wound bed. The white foam (polyvinyl alcohol, or Vers-Foam™ Dressing) is hydrophilic or moisture retaining. It is also an open pore foam, which allows for exudate to be removed. It has a higher tensile strength and is ideal for use in tunnels and shallow undermining. It also is pre-moistened with sterile water and is relatively non-adherent, making it beneficial for use on tendons, exposed hardware and exposed bone. It also is good for extremely painful wounds, shallow wounds and patients who are experiencing rapid granulation tissue growth.
