Ostensibly PVA sponge look like a solid block. Seen microscopically, however, about 90 percent of its volume is completely hollow, and the substrate that embraces the hollowness (pores) forms a three-dimensionally reticular structure, making the entire pores perfectly continuous.
This integral structure is the greatest characteristic of PVA sponge which allows it various functions.

PVA sponge is, quite different from common sponges such as urethane sponge, remarkably hydrophilic, and capillarity generated by its three-dimensional network of micropores produces outstanding water absorbent and water retention properties. Coming in contact with water makes the structure start absorbing water at an amazing speed, rapidly taking the water into itself and holding it securely.

When the wet, PVA pongr is soft, supple and resilient. So in scrubbing or wiping, it leaves no scratches on the surface of the pieaces it is working on.
Because of the soft and supple characteristics, it is uited for industrial uses such as cleaning of hard disks or silicon wafers, as well as for daily-life uses such as car care articles or powder puffs and sponge handkerchiefs.

A porous material that has uniform continuous pores using specila polyurethane and AION's original technology. Different from common polyurethane foam, AION PU sponge is hydrophilic and excels in water absorbing and water retaining properties.
