Sugi® sponge material is hydrophilic with an absorptive capacity that ranges from 1200% - 2100%.
Its hydrophilic and absorptive properties are presently being effectively used in the fields of eye surgery, ENT-surgery and various microsurgical procedures. The hydrophylic property is based on open pore structure, cellulose affinity to water, adhesion, cohesion and van der Waals forces. These forces also make it possible for Sugi® to exert sufficient absorptive propertives in presence of low amounts of water molecules, e.g. in 70% isopropanol (see absorption table).
The hydrophilic property combined with the open pore structure is the basis for excellent absorption of aqueous liquids.
