Can cellulose fibrils increase your factory's productivity?

By Justin Scarpello 10. October 2017

As a new boy in the world of cellulose fibrils, I am steadily getting an overview of what potential users of cellulose fibrils are interested in. The unique combination of properties that cellulose fibrils has is the obvious point most are interested in. In addition, the natural and renewable aspect to the material and the possibility to replace oil-based chemicals is becoming more and more important. But could there be more than that?

Surfactants – a tool to tailor surface chemistry of MFC?

By Rebecca Blell 22. August 2017

One of the advantages of cellulosic materials (including nanocellulose and microfibrillated cellulose (MFC)) compared to synthetic materials, is their environmentally friendly profile as well as their biodegradability. This profile is impacted by the number of chemical reactions the product will undergo during the manufacturing process. It would therefore be favorable to obtain desired chemical properties via physical adsorption instead of chemical reactions.

In this blog post, you will find examples on possible effects of surface adsorbed surfactants on cellulosic materials.

3 things to remember when using MFC in the lab

By Otto Soidinsalo 15. August 2017

Introducing a totally new material or technology to the market can often be challenging. Most people tend to have their favorite products which they know and prefer to work with. The natural way of testing of a new material is to compare it with the current products and apply the existing working routines to the first test runs. In some cases this approach might work but unfortunately in many cases it leads to a failure.

Today we will discuss about the important things that you should keep in mind when taking the first steps into the world of microfibrillated cellulose (MFC) and tell you how to gain the full potential out of it.

Microfibrillated cellulose (MFC) in future advanced wound dressing

By Harald G. Rønneberg 8. August 2017

Wound dressings are advanced materials designed for securing sufficient healing of exterior wounds. These dressings have been around for a while, often containing hydrocolloids to be able to protect and absorb moist as well as increase the wound healing speed.  I will  give you a short overview of what types of wound dressings that are available and how microfibrillated cellulose (MFC) may give a new addition to this field of technology.

Why does microfibrillated cellulose tolerate salts so well?

By Anni Karppinen 27. June 2017

Microfibrillated cellulose (MFC) differs from many rheology modifiers in that aspect that it can be used in high salinity formulations. The rheology effect comes from entangled fibers and salts do not influence this network as it does when the rheology effect is based on ionic interactions. However, the viscosity and other rheological properties vary slightly as a function of salt concentration. Let’s take a closer look at the reasons behind this.

Can I improve the strength of my products by using MFC?

By Mats Hjørnevik 20. June 2017

The ability of nanocellulose and microfibrillated cellulose to provide strength in different products has been discussed and studied for a long time. MFC fibers are strong and lightweight and has large surface area which makes it an excellent candidate for strengthening aid. Some are referring to the composites containing MFC as being “the next world-changing supermaterial” (Gizmodo, 2014), while others believe that they can be part of car production (Financial Post 2017). So how is this actually working?

Research review: Microfibrillated cellulose for bioprinting

By Anni Karppinen 13. June 2017

MFCResearchReviewIllustrationPhoto.jpgThree dimensional (3D) printing and tissue engineering are two fields that are currently developing rapidly and are both exciting technologies on their own. What if you combine them? That creates a new manufacturing process, bioprinting. It is a promising technology that might be the key to the on-demand tissue engineering. Microfibrillated cellulose (MFC) or nanocellulosic materials generally have an important role in the development.

Intimate relationships – cellulose and epoxy

By Lars Berglund 6. June 2017

Professor Lars Berglund, Head of the Biocomposites Division at KTH Royal Institute of Technology in Stockholm (Sweden), guides us through the relationship between cellulose and epoxy in this blog post. Not only do they matter, the properties created by this reaction are also excellent. Learn more about this in this weeks guest blog post.

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.

Sharper inkjet images without nozzle clogging

By Otto Soidinsalo 16. May 2017

Have you ever had problems with your inkjet printer? I bet that several people have experienced that during the years. The typical pattern is as follows: Your printer has been lying unused on your desk for weeks when suddenly you have an urgent need to print something. Often the outcome is that either the printing is messy or you end up having a blank paper in your hand. This is usually due to the drying of the ink on the printer head which is also known as nozzle clogging.
