Our Sugi® cellulose sponge material has an absorptive capacity ranging from 1200% - 2100% depending on the material specification.
We attribute this high absorptive capacity to the following physical properties: open pore structure, cellulose affinity to water, adhesion, cohesion and van der Waals forces Furthermore, the Sugi® sponge material will not only absorb liquids, it will hold and contain the absorbed liquid. The absorbed liquid can be released by applying pressure to the sponge material. However, due to the forces described above, a certain amount of the absorbed liquid will remain in the sponge material until it slowly evaporates.
The capability of absorbing and holding a specified liquid is crucial in certain applications.
Cataract surgery consists of about 85% of all ophthalmic surgeries. Sugi® Sponge is the leading material used for this surgery.
