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.

Why barrier properties of MFC may influence the taste & quality of your coffee

By Otto Soidinsalo 17. January 2017

The biggest change in the coffee culture in recent years has been the way people prepare their coffee at home. An increasing number of households use single serve brewing (pods, capsules) for producing a fresh cup of coffee, resulting in an increased amount of waste. Replacing the current coffee packing materials is not straightforward, and obviously there are several challenges related to it. In this blog post I will play with the idea how microfibrillated cellulose (MFC) could support the development of new, more environmentally friendly, compostable or biodegradable coffee capsules.

MFC commercial review: new industrial projects announced

By Mats Hjørnevik 10. January 2017

2017 looks exciting regarding the commercial use of microfibrillated cellulose (MFC). New industrial applications pop up regularly as the opportunities with MFC become clearer, and the availability of MFC improves. For example, MFC is known to strengthen composite materials, but the real value comes from the combination of properties that MFC can bring to certain applications, as demonstrated in the two examples below.
