Exilva® is Borregaard's innovative additive within the field of Cellulose fibrils / Microfibrillated cellulose (MFC). It is a natural and sustainable bio-based problem solver, that improves rheology and stability in product formulations. Through this blog you will learn more about the potential impact you can get from this wonderful product.


Lime, consisting of air lime and hydraulic lime, is one of the most important historical construction materials. Due to new plasticizer technologies available, we are now seeing a new golden era approaching for this material? Don't miss out on this Topic Tuesday subject that can give you insights into improving lime mortar formulations which can outcompete concrete materials by enhancing workability and appearance.

Trends are clear; today's technology demands expect smaller and lighter devices, while at the same time the need for digital speed, pace and stamina is a potential deal breaker. How do you cope with this when developing tomorrows technology? In today's Topic Tuesday we serve you some interesting thoughts on how to keep your batteries safer, so you can focus on staying in front in the ongoing development marathon.

How can I control the rheology of my concrete better?

Tania Risson, Guest Blogger | October 30, 2018


Concrete products are a complex mixture of chemicals, fines, and heavy particles. It's always challenging to control the stability, flow and strength of it. Many admixtures have been created to overcome these challenges, often containing synthetically derived performance additives. I will here try to give you some input of one of the new technologies and how it affects various parameters in the concrete.

For decades, producers of fluid materials have used HASE as the fundamental technology to control flow. How can new technologies complement this work horse of rheology modification? This week I am trying to uncover the key aspects of the HASE technology and give you ideas on the HASE technology in relation to the world I am familiar with: nanocellulose and cellulose fibrils. 

As a researcher, to have an overview of the alternatives available in your area of profession is of importance. In the landscape of rheology, new alternatives are emerging. In my short review today, I will grasp on the subject of similarities and potential synergies between two of the candidates you should note down: nanocellulose and hydrophobically modified ethoxylated polyurethanes (HEUR). Here are my hints and tips  on how to understand these two technologies better.

Rheology is the study of deformation and flow of material under stress, for example how easily material changes its form when it is pressed, or how easy it is to pump liquid in the pipes. Yield stress and viscosity are two importance aspects in the study of rheology and I will today exemplify this by using the Exilva microfibrillated technology. 

A fast viscosity recovery is good, and some times crucial, but that would also affect the leveling, right? In this weeks Topic Tuesday, we discuss how you can cope with the issue of getting fast recovery - and avoid sag - while getting your coating layer in level. We may also have some exciting ideas for you if you have problems with cracking. 

There is a growing interest to increase the portion of bio-based components in various consumables. We have previously discussed about the challenges to incorporate microfibrillated cellulose (MFC) into composite materials with hydrophobic matrixes, such as PLA. Today we will take a step even further and see how cellulose fibrils can support the development of more environmentally friendly tires with high performance and durability.

[VIDEO] Topic Tuesday: You need to change the way you think!

Suddenly, the new tax on pollutants in China, their ban on solvent based coatings for containers, and the city of Shanghais ban on solvent based coatings for exterior walls and wood ware has changed things. Do you want to know more on how to adapt in rapid market changes like these? In this topic Tuesday we are discussing this and showing you a couple of concrete examples to get your ideas start running. Don´t miss out on this weeks interesting discussion on saving business with the necessary level of innovation.
