Exilva MicroFibrillated Cellulose or MFC is a new performance additive made from natural raw materials, designed to outperform current oil-based technologies, in a more sustainable way.
The material is made from cellulose fibres, which are fibrillated (meaning that the fibre is split into a higher number of thinner fibres/fibrils). MFC is typically sourced from softwood and hardwood sources, as well as vegetable sources.
The multifunctionality of MFC enables it to partly take out stabilising additives like surfactants. In addition, MFC has shown potential as a strengthening additive (showing higher strength than Kevlar), barrier performance and filtering performance.
Exilva is an additive for a variety of applications, like coatings, adhesives, cosmetics, etc.. It is delivered as a 2% suspension, or a 10% paste. The dry film is a final product, which can be made from the suspension or paste, though it is not supplied by Borregaard.
