In this blog post we have collected our key learnings from working with corrugated board in over 170 trials. You will find information about reduced starch consumption, prolonged stability of viscosity in starch adhesives, robustness, increased productivity, bonding quality and how to fight warp. Finally, we share feedback and learnings from customers!

Mixing two liquids like oil and water is hard enough. At the same time keeping it stable, adds an additional level of difficulty in this challenge. And how can you reach the best performance on rheology and stability in the making of these emulsions? In this episode of Topic Tuesday, we are discussing the subject of emulsions; what are they, how do they work and how do we make them stable? Grab a coffee and joins us for a video session.
This month’s research review has some interesting news from the world of nanocellulose. We have referred to a lot of interesting functionalities from this exciting material before, ranging from 3D printing to super reinforcer and rheology additives. Today, we are giving you the news of an interesting, and, I must admit, slightly unforeseen idea. It was uncovered in Asia. Dig in to this week’s blog post from the Exilva blog to read more.
One of the benefits of highly fibrillated cellulose fibrils is its very high surface area. When the fibers are torn down to smaller and smaller fibrils, the surface area consequently increases, which leads to new properties and applications. Learn how its extreme water binding capacity, among other properties, may take your product to a new efficiency level.
Many reasons can lead to unstable formulations when you first start testing a new formulation or a new ingredient. Some are due to non-optimized use of ingredients such as stabilizers and others are due to formulation processing or incompatibilities. Sounds familiar? We might have good news for you.
Everyday life is full of formulations containing solid particles, pigments, beads or fillers. Depending on the application, the formulations may have a varying amount of solids. Common challenges with high solid content formulations are the settling of heavy particles or the floating of lighter ones. Therefore, it is important to ensure the stability of the solids suspended in a formulation. Especially those with high particle loading such as a coating formulation with matting agents, UV filters and other solids.
You may have read about the issues related to lithium-ion batteries lately. Situations where the batteries have swelled or even caused a fire or an explosion. The question is, could cellulose fibrils be used to prevent these issues? Or would there be other functions in the batteries where the fibrils would be useful or even open new opportunities?
Paint formulators face many challenges in today’s market, and are continuously in search of new innovative raw materials to satisfy the needs of their customers. In an effort to reduce cost, improve technical properties, and fulfill more stringent environmental regulations, chemists have started to look toward a class of products known as microspheres.
A familiar problem for producers of coatings and polyolefins is what literature calls blocking. When blocking occurs, it is the coatings ability to create adhesion to itself that causes the problems. There are many available technologies for avoiding this, in which some are synthetically derived, and others are derived directly from nature. Could a bio-based alternative give you the effect you are looking for? If you are looking for some ideas, this is the blog post to read.
Cellulose fibrils have been written and talked about for years. A substantial amount of reports have been written prospecting all sorts of application areas. Based on its functionalities, it seems to be a good rheology modifier, a good stabilizer and it is showing substantial strength enhancement. But is there any proof to the pudding and where do we find the latest developments? I have tried to gather a couple of relevant examples for you, which to me are fairly new developments. Dig into this week’s blog post to find out what they are!
Shotcrete is concrete or mortar pneumatically projected at high velocity through a nozzle. Its components are aggregates, cement and water, and it can be complemented by fine materials, chemical additives and reinforcing fibers. Shotcrete can be applied with mechanized equipment or manually, using wet-mix or dry-mix spraying. The choice of the spraying method depends on the dimensions of the project, the quantity of concrete to be applied, as well as the logistical and environmental circumstances. Some important properties of shotcrete are the appropriate consistency and early strength development in its fresh state as well as compressive strength and durability in its hardened state. Let´s discuss some basic properties and functionalities.
