PVA is optimal for water-absorbing rolls as it is excellent in hydrophilicity and water absorption. It provides high anti-abrasion and excellent durability in a water-retaining state.
The open-cell structure is used, which realizes lower resistance and excellent filtration. It can be adjusted to an open-cell size and shape.
Compared to the conventional PVA sponge, elasticity, water absorbing, and anti-abrasion have significantly improved. It provides a better performance as it can now remain clean when absorbing water.
Performance of a Water-Absorbing Roll = Water-Absorbing Capability + Drainage Capability
