Montmorillonite Clay (Bentonites) and cellulose fibrils

By Mats Hjørnevik 21. November 2017

Montmorillonite (Bentonite) clay and cellulose fibrils has a lot in common since they both can be used as a rheology modifier in different industries. However, there are also clear distinct differences. I aim to show you how I reflect on these two product technologies, and how you can look for synergies and new innovations when using cellulose fibrils and clay. I will first review the non-soluble nature which is common for these materials and then show how this is reflected in the rheology and stability properties of each. I will also focus my discussion on the bentonite branch of montmorillonite clays due to its similarities with the cellulose fibrils

MFC and its resistance to heat: Can it create opportunities?

By Mats Hjørnevik 23. May 2017
Microfibrillated cellulose is an interesting rheology additive in several aspects due to its multi-functionalities. It can create pseudoplastic behaviour in flowing systems, prevent cracking of curing systems, improve barrier properties of cured systems, just to name a few opportunities. However, one of its less known characteristics is its ability to perform under a range of different temperatures, without losing the ability to provide the desired viscosity profile. I will in this week’s post focus on how MFC performs at high temperatures in the liquid phases and how it performs in comparison to more well-known rheology additives.
