Description

CELLULOSE FIBRILS

Borregaard’s Exilva® MFC enhances structure in your product formulations, increasing your formulation efficiency and reducing your CO2 footprint.

Exilva is a new type of bio-based additive, sourced from Norway Spruce in Scandinavian forests. The new-to-the-market technology is showing some clear advantages, helping you out when formulating.

It is an insoluble microfibrillated cellulose, which consists of an entanglement of the cellulose fibers which has the ability to interact both physically through its extreme surface area and chemically through hydrogen bonding. Its novel nature gives it rheological and mechanical functionalities, which as an additive, imparts a unique combination of properties in finished product systems.

As a result of the fibrillation process, many hydroxyl groups become accessible to matrix in a network, resulting in a very high water retention capability. MFC will also retain its crystallinity features after the production process, providing a robust product.

WHAT IS EXILVA?

Exilva is a new type of bio-based additive, sourced from Norway Spruce in Scandinavian forests. The new-to-the-market technology is showing some clear advantages, helping you out when formulating.

The many benefits Exilva can deliver include improved performance in anti-settling and anti-sedimentation through improved yield stress, versatility and flexibility in formulations through robustness to shear, pH and temperature, as well as improving the sustainability profile.

HOW DOES IT WORK?
Exilva is an insoluble Microfibrillated cellulose, which consists of an entanglement of the cellulose fibers which has the ability to interact both physically through its extreme surface area and chemically through hydrogen bonding. Its novel nature gives it rheological and mechanical functionalities, which as an additive, imparts a unique combination of properties in finished product systems.

As a result of the fibrillation process, many hydroxyl groups become accessible to matrix in a network, resulting in a very high water retention capability. MFC will also retain its crystallinity features after the production process, providing a robust product.

The field of Microfibrillated cellulose has been known since the early 1980’s and has been reported several times in literature. Research on MFC has previously been confined to small laboratories and pilot plants, due to constraints in technology and production feasibility. Through its proprietary technology, Exilva, Borregaard is now able to provide high quality Microfibrillated cellulose, from its production plant in Sarpsborg, Norway.

BENEFITS FROM TAILORED FUNCTIONALITIES
Exilva is Borregaard’s innovative new product within the field of Microfibrillated cellulose (MFC), which not only offers rheology modification, but also a long list of other advantages in a material that demonstrates high efficacy and robustness in harsh environments.

Through Borregaard’s proprietary fibrillation process, cellulose fibres are converted into a 3D network of microfibrils, with an ultra-high surface area and water retention capability, that will retain their crystallinity features even after the production process.

In addition to superior rheology performance, Exilva also improves product stability (anti-settling) and versatility, alongside controlling dry-out time, improving barriers and enhancing uptake of active ingredients. Its pseudoplastic (non-newtonian) performance makes Exilva ideally suited to products where strict demands are made to spray quality and Exilva is particularly suited when low viscosity at high shear and/or rapid recovery of viscosity is required.

Extremely shear thinning (Pseudoplastic, non-newtonian)
High viscosity at low shear
Thixotropic characteristics
Very high water retention capacity
Barrier properties
Enhancing uptake of active ingredients
Ensuring stability
