Betafib MCF

Betafib is a micro cellulosic fibre derived from vegetable raw materials. Throughout our patented processing this 100% natural biopolymer is not chemically modified. It delivers high suspension efficacy and at the typical low dosage levels it becomes a cost efficient enabling technology.

Rheology modification
The excellent shear thinning and 3D structuring behavior of Betafib is caused by its specific morphology at micro scale level.

Rheology modification
The excellent particle carrying properties result from the 3D structuring behavior of Betafib. This results from the patented process that gives Betafib its specific morphology at micro scale level.

    Betafib shows a distinct yieldpoint 
    The plateau leading to the yieldpoint indicates a stable gel-like behaviour 
    The steepness of the slope after the yieldpoint represents the strong fluidlike behaviour (high pourability) 
    The network rebuilds within seconds (not shown on graph) 

Environmental profile
Betafib is made from renewable vegetable resources and does not contain any hazardous components.
Betafib is inherently biodegradable and will decompose to carbon dioxide and water. The slow biodegradation gives the product a degree of microbiological stability.

Fibres from a network: Betafib

Betafib is a success story. It is a micro-cellulose fibre made from vegetable residual flows. As part of the BioFib project, researchers have studied whether the fibre can be used in paints and liquid detergents.
‘We found that this micro-cellulose fibre formed a fine, invisible network when at rest,’ explains CornĂ© Meeuwissen, a biobased innovations developer at Cosun. He has been engaged in the Betafib project since the very beginning and is still involved in its technical and commercial development. ‘The network catches small particles that are held in suspension, as it were, to create a homogenous substance. You can compare it with a dressing with small pieces of vegetable suspended in it. If you try to pour it, it turns into a liquid and comes out. Our material has that property, too. It can form a network and catch particles even at low doses. But when it is disturbed it turns into a liquid again. A fantastic property!’

The interest in Betafib is huge. Manufacturers of detergents, paints and coatings and the oil and gas industry are working with Cosun Biobased Products on new applications. ‘There is a trend towards liquid detergents,’ says Meeuwissen. ‘The particles must be evenly distributed. Betafib makes sure they are. Heavier pigment particles in paints subside and a layer of water appears on the top of the paint. That’s why you have to stir it before you can use it. With Betafib you don’t have to. For the industry, this is a distinctive sales argument. In oil flushings, finally, Betafib combines pollutants such as sand and minerals together. Betafib also has excellent properties to resist heat and extreme pH values deep underground.’

Cosun Biobased Products is working on this project at its pilot plant in Roosendaal. It will be scaled up to produce Betafib in larger volumes. ´Cooperation with potential customers is vital to the project’s success,´ explains Meeuwissen. ´They provide essential feedback. So do our partners in BIOCAB. We constantly receive specialised knowledge from them. We use beet pulp all year round. A microbiological process begins when we store the beet pulp in silos. Part of our work was to find out what effect it had on the quality of the pulp fibres. We received many useful tips from BioClear, which has a great deal of expertise in microbes.’
