Exilva Microfibrillated Cellulose vs. Fumed silica: anti-settling benefits from effective yield stress

By Mats Hjørnevik 11. June 2019

Exilva microfibrillated cellulose and fumed silica are both used for controlling the rheology of liquid systems, such as anti-settling and anti-sedimentation. But when we are comparing the two technologies, we also see differences. In this article, we will show you how the microfibrillated cellulose and fumed silica builds yield stress, and how they consequently can give good anti-settling and anti-sedimentation benefits.

How to use Cellulose fibrils with foam forming surfactants

By Rebecca Blell 29. May 2019

Surfactants are present in most consumer products. The most familiar examples are shampoos, hand wash products and cleaning products in general. Switching to sulfate free surfactants improves the environmental profile, but can be a challenge. Let me show you a way to this.

I will demonstrate that one can use cellulose fibrils to thicken and stabilize formulations with foam forming surfactants. The most important point to remember when preparing such formulations is to avoid foam formation during the incorporation step of surfactants with the cellulose fibrils.

Topic Tuesday: Next generation gypsum boards

By Mats Hjørnevik 16. April 2019

Gypsum boards (plasterboard/drywall) are a very commonly used product in the construction industry. Currently, the production of the boards is a labor-intensive, CO2 producing and energy consuming process with the need for many synthesized additives to retain the flow, strength and setting profiles. What if you could change that?

Sedimentation Stability: The Importance of Yield Stress and Storage Modulus

By Jochum Beetsma 11. April 2019

Sedimentation of solid particles in liquid materials, like paints and inks, is caused by gravitational force pulling particles of high density down. In the worst case, sedimentation can result in settling, the formation of a hard layer of solid material on the bottom of the can. How to avoid this?

Innovation and Business Performance: Choose the right approach

By Andrew Wright 26. March 2019

The investment in change needed for high business performance in five years will compromise business performance in the short- to medium-term. The trade-off facing the Executive of any organisation is between investment in strategic goals and delivering acceptable (‘survival’) performance in the meantime. Here are 4 high-level approaches you should consider – and a hot tip from our side.

How to determine a product’s environmental performance

By Andreas Brekke 19. March 2019

The scientific method Life Cycle Assessment (LCA) is a tool originally developed to scrutinize the environmental performance of products, product systems or services. In recent years, the LCA framework has been expanded to include all aspects of sustainability. This blog post will present what LCA is, how it has developed historically and why you should care about it.

What is sustainability, really?

By Andreas Brekke 12. March 2019

Often the word sustainability is used to designate that something is good, without any specification of good for what or good for whom. It’s time to put some hold to the phrase ‘sustainable’. Learn more on what it means and what you need to keep in mind when talking about sustainable products or solutions.

Are you making products with markets in winter harsh areas, and depend on freeze-thaw stability?

By Rebecca Blell 5. March 2019

When most people were talking about the brutal polar vortex that hit Chicago earlier this year, I am sure many were looking for ways to best protect the products they are producing, transporting, storing and using from being destroyed by freezing. In this blog post, I will briefly mention a few tips on how to make products freeze-thaw stable such that they can be used in winter harsh areas.

How has China become leading in sustainable technologies?

By Mats Hjørnevik 20. February 2019

In China we are currently seeing a massive shift towards sustainable technologies. Many are describing China as the next green superpower, and that China is positioning itself towards a new area where the accessibility to energy is becoming very different from the current situation. This can shift the power balance towards economies which embrace the new opportunities from more sustainable solutions. Where can you find opportunities in this? And are there opportunities for novel sustainable materials like cellulose fibrils and microfibrillated cellulose (MFC)?
