Betafib MCF

Betafib is a cellulosic microfiber derived from vegetable raw materials. It is a 100% natural biopolymer and has not been chemically modified. Due to refined extraction and processing methods, Betafib delivers high viscosity at low dosage levels, is shear thinning and has a high yield stress. Moreover, Betafib is very stable at a
broad pH and temperature range

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.
