Exilva Microfibrillated Cellulose & Clay Platelets: anti-settling & anti-sedimentation because of yield stress

By Mats Hjørnevik 9. July 2019

Clay (including montmorillonite and bentonite) additives and Exilva microfibrillated cellulose (MFC) have a lot in common since they both can be used as rheology modifier in different industries. However, there are also clear differences. In this article, I will review the ability of the materials to provide yield stress and subsequent anti-settling & anti-sedimentation benefits. Tune-in on a comparison between two of the most potent anti-settling & anti-sedimentation additives available.

Why cellulose fibrils (microfibrillated cellulose) will make a difference in coatings

By Mats Hjørnevik 29. January 2019

Coating performance is often very complex, and can depend on the coating system itself, substrate to be coated, conditions during coating etc. Increasing the performance is often a lengthy process with multiple tests on wet paint performance and dried coating performance. Key aspects of wet paints can be control of rheology, and for solid coatings the ability to improve endurance. Are there technologies available for aiding on the key aspects? For sure. Are there new sustainable additives which can improve the new water borne technologies? Let me show you an example of exactly that in this blog post.

Focus on sustainability is changing business!

By Mats Hjørnevik 18. December 2018

We are starting to see major shifts towards increased focus on sustainability, with examples like the likely upcoming EU ban on single use plastics, and the Chinese environmental tax on solvent based coatings. Your company and its competitive advantage will be defined by the ability shown in adapting to this. I will in this blog post touch upon a subject that can be important to assess for you going forward.

How to compare rheology additives: The example of nanocellulose/cellulose fibrils and HASE

By Mats Hjørnevik 23. October 2018

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.

High performance and durability with greener tire tread

By Otto Soidinsalo 2. October 2018

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.

I need to improve the strength of my products, how can I do this?

By Mats Hjørnevik 18. September 2018

There are several solutions to improve strength performance, and there are new materials available on the market. But how do you find the reinforcement additives and agents that provides the benefits you are looking for? And can this be done inline with the increased demand for sustainability at the same time? Spend a couple of minutes on this weeks blog post, and get some inputs and ideas on what to expect from one of these new materials.

Research review August 2018: new nanocellulose findings

By Mats Hjørnevik 4. September 2018

This month’s research review has some interesting news from the world of nanocellulose. We have referred to a lot of interesting functionalities from this exciting material before, ranging from 3D printing to super reinforcer and rheology additives. Today, we are giving you the news of an interesting, and, I must admit, slightly unforeseen idea. It was uncovered in Asia. Dig in to this week’s blog post from the Exilva blog to read more.

How to avoid unstable formulations

By Rebecca Blell 21. August 2018

Many reasons can lead to unstable formulations when you first start testing a new formulation or a new ingredient. Some are due to non-optimized use of ingredients such as stabilizers and others are due to formulation processing or incompatibilities. Sounds familiar? We might have good news for you.

How to counteract formulation settling issues

By Rebecca Blell 14. August 2018

Everyday life is full of formulations containing solid particles, pigments, beads or fillers. Depending on the application, the formulations may have a varying amount of solids. Common challenges with high solid content formulations are the settling of heavy particles or the floating of lighter ones. Therefore, it is important to ensure the stability of the solids suspended in a formulation. Especially those with high particle loading such as a coating formulation with matting agents, UV filters and other solids.

How can I make my batteries safer?

By Otto Soidinsalo 7. August 2018

You may have read about the issues related to lithium-ion batteries lately. Situations where the batteries have swelled or even caused a fire or an explosion. The question is, could cellulose fibrils be used to prevent these issues? Or would there be other functions in the batteries where the fibrils would be useful or even open new opportunities?
