Looks like solid sponge, but ,on the microscopic level, PVA sponge is interconnected hollow cells and 90% of volume is air. Open pores are connected three dimensionally to connect each cells to continuous ones.
This physical structure is the most remarkable feature of PVA sponge and delivers various functions.

Unlike ordinary urethane sponge, PVA sponge is extremely hydrophilic and possesses impressive retention, because of capillarity caused by micro open pores connecting in all directions.
Elasticity and tensile properties helps safe application without giving any harmful effects
especially when used as cleaning or wiping purpose.
This feature is suitable to industrial uses, such as cleaning hard disks or silicon wafers,
as well to daily-life uses, such as cleaning tool for cars,
cosmetic puffs and sponge tissues.
Aion continuously developes New Porous Material, such as PU sponge and Polyolefin sponge by original technology.
Using specific urethane materials, unlike ordinary urethane foam, hydrophilic and highly absorbent, resists against heat, alcoholic, acid, and alkaline fluid.Keeps flexibility and elasticity even under dry conditions
Resist against strong acid,
strong alkaline, heat and hot water.
Highly hydrophilic and long-lasting.
Keeps flexibility and elasticity.
