The Strength of CEBINA

Nature’s own rebar, cellulose nano fibrils (CNFs), gives all plants their incredible strength – on land and sea – from towering trees to tiny sea algae. Millions of tiny fibrils bundle together to form a single fibre, creating a naturally reinforced structure. If all the CNFs in a single gram of wood were placed one-by-one after each other, they would form a line that travels around the world’s circumference more than seven times!

We unwind wood fibres to release the potential of CNFs!

CEBINA is Norske Skog’s CNF-variant!
And CEBINA MB is our unique, water-free solution!

Weaving a flexible network using nature’s rebar

Due to cellulose’s high crystallinity, the individual CNFs have tensile strength multiple times higher than iron, and can withstand high temperatures, volatile pH and very saline environments. This means that there is a broad range of systems where CEBINA can impart their functionality – thixotropic rheology, membranes, reinforcement. Uniquely, we have utilized these properties to create water-and solvent-free masterbatches that allow CEBINA to be added to epoxy, polyurethane, and many other systems!

Just a small dose of CEBINA into a suspension creates a spontaneously assembled network that thickens the system while remaining flexible. This network is key! Unlike many other conventional additives, CEBINAs rheology control is largely unaffected by temperature and pH, and instead adapts to shear forces, making sprayable coatings more stable—even on angled surfaces like walls and ceilings. When dried, the network is maintained. This can introduce membrane properties or improve strength and bonding in in paper, fibreboards, cement and a variety of other materials.

When drying CEBINA, the nano fibrils locks strongly together, producing a matrix similar to glass fibers or Kevlar. These interlocked fibrils are stiff, lightweight and have eight times the tensile strength of steel. This effect applied to paper increases surface and tensile strength, and CEBINA can provide similar strength enhancement in concrete, glue, paint, fiberboards and more.
