Vyon® manufactured from HDPE (High-Density Polyethylene) and & UHMWPE (Ultra-High Molecular Weight Polyethylene), is naturally hydrophobic and designed to pose difficulty for water and aqueous solutions to pass through or to be absorbed into the porous structure when required. Using a vacuum deposition process, the surface energy of Vyon and its internal tortuous structure can be altered to promote hydrophilic characteristics and allow the material to wet out when in contact with water or other aqueous solutions.
