Why new materials can play an important role in new innovations

By Mats Hjørnevik 18. April 2017

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.

Is MFC compatible with surfactants?

By Rebecca Blell 11. April 2017

Have you run into problems with incompatibilities between the surfactant you would like to use and other ingredients in your formulation? This is a common problem since surfactants are quite versatile in charge and chemical structure as well as in functionalities. This could for example lead to undesired interactions with oppositely charged ingredients.

In this blog post I will try to explain why this would not be an issue when you are planning to introduce microfibrillated cellulose (MFC) in your surfactant based system. You will also find a few recommendations on do’s and don’ts when mixing MFC and surfactants.

Market & research review: nanocellulose and MFC is THE hot topic

By Mats Hjørnevik 21. March 2017

A lot of work on the MFC and nanocellulose is going on in an increased amount of business fields, all over the globe. We have seen a significant pick up in the strength and reinforcement functionalities of microfibrillated cellulose during the last 6-12 months, where its ability to provide significant strength improvements is clear. This week we have collected three new interesting areas of giving strength and barrier improvements, with exciting opportunities like bone construction with 3D printing, carbon fiber replacement, and water purification. This is your Exilva blog on exciting innovation, don’t miss out on our collection of news this week, and enjoy your reading!

Microfibrillated Cellulose as a biofiller for greener tire tread

By Otto Soidinsalo 7. March 2017

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 to even further and see how MFC can support the development of more environmentally friendly tires with high performance and durability.

Having trouble of producing stable foams?

By Anni Karppinen 28. February 2017

Making foams, in other words introducing gas in a solid or liquid, is needed in industries like construction, composites, home care and personal care. Solid foam is a clever way to produce lightweight structures and insulation materials, whereas many personal care and detergent formulations are required to form a liquid foam. To produce solid foams, you need a blowing agent which introduces gas bubbles in the solid and a solid (often a polymer) that hardens around them. Liquid foams are mainly created by using surfactants and mixing air in. Earlier on this blog, we have explained how microfibrillated cellulose can be used for creating bubble-free gel coats. Could it also help forming intentional foam structures?

How MFC can improve durability and performance of your boat

By Synnøve Holtan 14. February 2017

In my previous blog post, I covered the characteristics of microfibrillated cellulose (MFC) and fumed silica as raw materials used for industrial purposes. I focused on how MFC provides a viable alternative to fumed silica in many applications since they both have large surface areas with similar surface active groups. However, the physical network properties of the two materials differ and may lead to new and exciting discoveries in the end products.

Three reasons why water-borne product systems are taking over

By Mats Hjørnevik 7. February 2017

You may have noticed that the number of waterborne systems has increased massively during the past decade. Waterborne systems, like paint and adhesives, where water is the main part of the product in many cases, are popular due to several factors. My goal with this article is to introduce you to what I believe are the three most significant aspects of the increased demand for waterborne product systems, focusing on coatings and adhesives.

Sustainable composites: the compatibility between PLA and MFC

By Otto Soidinsalo 31. January 2017

The market for packaging and packaging solutions is expected to grow in the next four years due to factors like increased online shopping*. At the same time, the demand for sustainable packaging becomes more evident. In this article, we explore the compatibility of MFC with PLA and discuss what could be the benefits of such a mixture in various packaging products.

Why is microfibrillated cellulose translucent and not transparent?

By Anni Karppinen 24. January 2017

From time to time I get comments from people interested in microfibrillated cellulose (MFC) that they cannot dissolve the product, and the formulation remains hazy no matter how much they mix. Alternatively, they ask how low the concentration needs to be to get a transparent formulation. The answer to these questions is that microfibrillated cellulose does not dissolve in water (or in common solvents) which means that it does not make a transparent solution, no matter how much it is mixed or how low concentration is used. There is no need to worry, however; the non-dissolved fibers are the key factor to the interesting behavior of MFC. Let’s look at the translucency of MFC in more detail.
