Multifunctionality

Exilva is Borregaard’s innovative new product within the field of Microfibrillar / 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.
