Class: Cellulase
Format: Liquids
FiberCare® U
Novonesis Fibercare® U is especially suited to improving the strength of bleached and unbleached paper and board. It's a single-component cellulase, giving you more control over fiber properties. It also helps you to achieve more cost-effective production.
Product features, details and benefits
- Chemical savingsThis product improves the runnability and strengthening potential of fiber. That means it may complement, reduce the need for, or even replace common chemistries. These include starch, dewatering aids, strength resins and debonders.
- Fiber savingsThis product improves the bonding and strengthening potential of fiber. This upgrading allows you to replace costly fibers with more economical ones. It also allows you to lightweight; meet end-product performance specifications with less fiber. By allowing you to increase the share of fillers in your final products, it enables reduced fiber use.
- Improved paper & board strengthThis product modifies the fiber surface to improve fibrillation and other properties. This leads to better fiber-to-fiber bonding. The result is stronger paper and board.
- Refining energy savingsEnergy-intensive mechanical action during pulp refining develops properties needed for better fiber bonding. This product enhances fiber's response to refining and reduces the energy needed to meet strength specifications in paper and board. It also helps debottleneck your refining step.
Fibercare® U enables fiber, chemical and energy savings. It allows you to increase production and improve end-product quality. It tolerates higher temperatures and lower pH applications.
This product contains enzymes. While enzymes are safe to use in consumer applications, they need correct handling in working environments to ensure workers’ safety.
Indeed, repeated inhalation of enzyme dust or aerosols resulting from improper handling may induce sensitization and may cause allergic type 1 reactions in sensitized individuals.
Please follow the precautionary handling recommendations below:
- Avoid breathing dust/fume/gas/mist/vapors/spray
- Avoid contact with eyes, skin, or clothing
- In case of inadequate ventilation wear respiratory protection
- IF INHALED: Remove person to fresh air and keep comfortable for breathing
- If experiencing respiratory symptoms: Call a POISON CENTER or a doctor
- Store in a dry place. Store in a closed container
- Dispose of contents/containers in accordance with local regulations
For recommendations on how to safely handle the enzyme product, please visit the guide.
How cellulases improve paper and board strength
Through controlled action on cellulose on the fiber surface, cellulases improve interfiber bonding potential. That enhances paper & board's strength and structure.
The nature of the fiber surface plays a key role in the strength and structure of paper and board. Cellulases modify accessible cellulose on the fiber's surface. This controlled action gives the fiber surface new chemical and structural properties. Cellulases enrich key chemical functional groups and generate fibrillation on the fiber surface. That improves the refinability and strengthening potential of the pulp.
Mechanical refining may impact the integrity of the entire fiber wall. By contrast, enzymatic modification is a mild treatment that acts on the accessible surface. And unlike chemical strengthening additives, enzymatic treatment unlocks the fiber's own strengthening potential.
Testing one of our products in your own production is the best way to experience all the benefits.
