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.

Topic Tuesday: How to perform with your oil-in-water-emulsion

Mixing two liquids like oil and water is hard enough. At the same time keeping it stable, adds an additional level of difficulty in this challenge. And how can you reach the best performance on rheology and stability in the making of these emulsions? In this episode of Topic Tuesday, we are discussing the subject of emulsions; what are they, how do they work and how do we make them stable? Grab a coffee and joins us for a video session.

Research review August 2018: New nanocellulose findings

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.

3 great ways to exploit the large surface area of cellulose fibrils

One of the benefits of highly fibrillated cellulose fibrils is its very high surface areaWhen the fibers are torn down to smaller and smaller fibrils, the surface area consequently increases, which leads to new properties and applications. Learn how its extreme water binding capacity, among other properties, may take your product to a new efficiency level.

My coating is seeing blocking issues; but what’s my option dealing with it?

A familiar problem for producers of coatings and polyolefins is what literature calls blocking. When blocking occurs, it is the coatings ability to create adhesion to itself that causes the problems. There are many available technologies for avoiding this, in which some are synthetically derived, and others are derived directly from nature. Could a bio-based alternative give you the effect you are looking for? If you are looking for some ideas, this is the blog post to read.

Research Review June 2018: new technology is being created, and cellulose fibrils is participating

Cellulose fibrils have been written and talked about for years. A substantial amount of reports have been written prospecting all sorts of application areas. Based on its functionalities, it seems to be a good rheology modifier, a good stabilizer and it is showing substantial strength enhancement. But is there any proof to the pudding and where do we find the latest developments? I have tried to gather a couple of relevant examples for you, which to me are fairly new developments. Dig into this week’s blog post to find out what they are!

Trouble with cracking during drying of your coating, adhesive, putty or other products?

One of my favorite characteristics of the cellulose fibrils is its behavior when drying or involved in the drying process of a product system. I have learned through some of our conducted tests that cellulose fibrils can act in an interesting and often beneficial way towards obtaining desired end product characteristics. Most of the examples on how the fibrils influence the drying are related to coatings. I however believe that similar behavior is possible to observe in application areas where a tight control of dry-out properties is desired. Evaporation of solvents is often the main technique for drying in many applications. I will therefore focus my blog post this time on this specific drying technique. Let me share some very interesting insights into why cellulose fibrils are improving the products upon drying.
