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

19. November 2019

Hydroxyethyl cellulose (HEC) and Exilva microfibrillated cellulose (MFC) can both be used as rheology modifiers in a variety of industries to prevent sedimentation and settling. In this article, I review the ability of the materials to give a yield stress in a waterbased system and, because of that, provide anti-settling and anti-sedimentation behavior. Tune-in on a comparison between these two rheology additives.

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

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.

Exilva Microfibrillated Cellulose vs. Fumed silica: anti-settling benefits from effective yield stress

Exilva microfibrillated cellulose and fumed silica are both used for controlling the rheology of liquid systems, such as anti-settling and anti-sedimentation. But when we are comparing the two technologies, we also see differences. In this article, we will show you how the microfibrillated cellulose and fumed silica builds yield stress, and how they consequently can give good anti-settling and anti-sedimentation benefits.

Topic Tuesday: Next generation gypsum boards

Gypsum boards (plasterboard/drywall) are a very commonly used product in the construction industry. Currently, the production of the boards is a labor-intensive, CO2 producing and energy consuming process with the need for many synthesized additives to retain the flow, strength and setting profiles. What if you could change that?

How has China become leading in sustainable technologies?

In China we are currently seeing a massive shift towards sustainable technologies. Many are describing China as the next green superpower, and that China is positioning itself towards a new area where the accessibility to energy is becoming very different from the current situation. This can shift the power balance towards economies which embrace the new opportunities from more sustainable solutions. Where can you find opportunities in this? And are there opportunities for novel sustainable materials like cellulose fibrils and microfibrillated cellulose (MFC)?

Why new materials can play an important role in new innovations

Solving problems you have or initiate new innovations can lead down quite different paths. Sometimes the urge to get rid of a problem can lead to many quick decisions, but what should one really look for in these types of situations? Should your standard tool box of problem solvers be used, or do you have the opportunity to focus on upgrading this box? In this blog post, I will try to show you some concrete examples why adding new tools to your tool box can improve your functionalities beyond your scope, using the microfibrillated cellulose as an example. Simply, why new functionality beats substitution.

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

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.
