Electron Beam (EB) Crosslinked Sodium Carboxymethyl Cellulose Gel

Gels Formed without Additive

After mixing a water soluble polymer such as polyvinyl alcohol (PVA) to create a paste, processing with electron beams causes crosslinking resulting in a hydrogel.
It is possible to form gels using only water and polymer so there is no need to worry about additive release. That is why electron beam crosslinked PVA gel is used to dress wounds to promote therapeutic effects.
We manufacture and sell electron beam crosslinked CMC gel made from sodium carboxymethyl cellulose. This is used as an ingredient in sprayed paper and by spreading on concrete surfaces it is used to limit quality reductions such as loss of strength and cracks that form from sudden drying.

CMC Gel Applications as a Sprayed Paper Ingredient

Improved Paper Strength and Adhesion to Uneven Surfaces

Sprayed paper coating materials using our CMC Gel are used by SEIREN KST Corporation in their "Washi Shokunin" product.
"Washi Shokunin" is a coating material with paper sprayed directly on walls and solid objects. By mixing CMC gel in with the paper pulp, it is possible to improve the strength of the paper and help it to adhere to uneven surfaces. Example uses include lampshades for atmospheric lighting, and to lessen solar light and block views from outside by spraying on large glass surfaces in residential contexts.
