Applications for strong, lightweight MFC films

7. January 2020

Microfibrillated cellulose (MFC) has a good film-forming ability, where the film is strong and light. In addition, the films are opaque, translucent or even transparent depending on the thickness of the film and type of MFC. They also show good oxygen barrier properties. Moreover, MFC can be combined with different polymers or fillers to obtain even more versatile material. In this post, we want to show the potential of MFC films in various applications. Let’s start by discussing how MFC films can be made and then see what kind of applications these films may have.

I am looking to improve my rheology in difficult ph ranges: where do I look?

Controlling rheology in very acidic or alkaline environments can be a tricky challenge. Different products ranging from examples like concrete to, your household cleaning products, are very different on pH. Extreme pH conditions can decrease the efficiency and functionality of some rheology additives, but there are some available alternatives. This post will try to give you some ideas on how the technology of cellulose fibrils can interact in your formulation and make sure you stay in control over your product´s rheology under difficult circumstances. And why is this ability from the cellulose giving you this benefit?

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.

How to improve art conservation by utilizing the technology advantage

OK, so this case fascinated me a great deal. I have previously learned a lot on film forming properties, oxygen barrier properties and other related topics to this in the past. But recently I learned that the properties from microfibrillated cellulose and cellulose fibrils is starting to show potential in art preservation or conservation. But how does this take place, and what’s the main functionalities behind all this? I spent some time researching the subject, and today I am sharing my findings with you. Some key words: stability, transparency and mechanical strength. Dig in to learn more!

Cellulose fibrils for printed electronics

Printed electronics suit well for the current mega trends, like internet of things and growing interest in monitoring your own health. The products produced by printed electronics vary from displays and sensors to energy storage and flexible conductors. For example, small sensors can be printed on food packaging to follow the quality of food as well as warn the consumer when the product is out of date. For such reasons, the interest for developing materials for printed electronics is growing. How can cellulose fibrils and other cellulose based materials be used in such applications?

Stability of Cellulose fibrils — microbial degradation

Cellulose fibrils are most often supplied as readily activated water suspensions. This maintains the product’s performance and makes it easy to incorporate into a formulation. It however brings up questions about the microbial stability of the suspension over time. Is the robustness of Cellulose fibrils enough in this case?
