Bring your corrugated starch adhesive robustness to a new level with Exilva MFC

26. May 2020

In a previous blog post, I explained how the new technology of Exilva microfibrillated cellulose may improve the viscosity stability of starch adhesives. Here is the second blog post in the corrugated boards application series, and now I have entered the glue kitchen of a corrugated boards manufacturer to evaluate the robustness and stability effects of Exilva.

Can Exilva be used with Quaternary ammonium compounds?

Quaternary ammonium compounds (QACs) are a group of cationic antimicrobials widely used for numerous industrial and pharmaceutical purposes. They are disinfectant chemicals commonly used in disinfectant wipes, sprays and household cleaners. They are very popular these days as they allow products to claim to be antibacterial and are part of many EPA listed products with emerging viral pathogens and human coronavirus (Covid-19) claims.

Can Exilva MFC be used in high alcohol based products such as hand sanitizers?

Hydroalcoholic hand sanitizers are the best option to keep up your hand hygiene when soap and water are not accessible. They are one of the most used and needed products these days. If you are considering formulating a hand sanitizer, read about how you can use Exilva Microfibrillated Cellulose, a biobased material, to structure and thicken your formulations as well as provide a non-tacky feel.

A way to reach prolonged stability of starch adhesives

Starch is a natural polymer found in many processes either as an adhesive or a thickener. Following paper production, corrugated board is the second largest application of non-food starches globally, where it it used as an adhesive between the fluting and liners. The control of the adhesive viscosity during process and storage is critical. However, despite further developments regarding the formulation of starch adhesives, the viscosity is commonly not stable enough over extended periods of time, in particular over weekend storage. In this first of a series of blog posts with the corrugated boards application as the example, I will give an introduction to this problem, and the new technology of Exilva, a microfibrillated cellulose, to solve it.

Innovation – developing core business versus risk mitigation

Most innovation is focused on improving core business, both in small increments and large jumps, to keep ahead of competitors. Disruption can make such innovation worthless e.g. in 2004, wet film photographic technology was overwhelmed by digital photography.

In this article we look at how innovation is becoming a vital part of corporate risk management, developing alternative survival strategies as disruptive changes hit organisations.

Innovation talk: Is your business a dinosaur or a bird?

Faced with disruptive changes to the economic environment, only those businesses that are flexible and responsive can survive and prosper. Those not responding quickly enough will die off like the dinosaurs, but it’s getting harder to react enough in time – now you need to pre-empt change.

This article continues to illustrate the risks of not being ahead of the game so looks at investing wisely in exploiting advances in materials and technology to survive and prosper, like the birds.

Applications for strong, lightweight MFC films

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.

Exilva Microfibrillated Cellulose & Hydroxyethyl Cellulose: anti-settling & anti-sedimentation because of yield stress

Hydroxyethyl cellulose (HEC) and Exilva microfibrillated cellulose (MFC) can both be used as rheology modifiers in a variety of industries to prevent sedimentation and settling. In this article, I review the ability of the materials to give a yield stress in a waterbased system and, because of that, provide anti-settling and anti-sedimentation behavior. Tune-in on a comparison between these two rheology additives.

How yield stress play an important role in anti-settling in your paint

Undesirable phenomena such as sedimentation and settling can often occur during the storage of paints. Therefore, a re-dispersion step is necessary which can mean additional cost. These challenges can be even more pronounced in high solid content formulations and so it is crucial to secure stability of those systems. To avoid these effects, rheology modifiers need to be added to paint formulations. So, I prepared some information for you and conducted a couple of tests with the rheology additive nanocellulose to show you how focus on yield stress will reduce sedimentation and settling.
