Fraunhofer Institute of Process Engineering and Packaging IVV is studying the extraction process for biowax production and the development of biowax dispersions from it.
form a thin layer of wax to protect itself from drying. So far, this natural renewable raw material has hardly been used in
Chinese
. However, in the future, it can be considered a form of sustainable coating. It can be used to coat film and paper surfaces for water vapor barrier and to make them water resistant. In order for these dispersions to be processed in industrial equipment, they must be stabilized. For Candelilla wax, this has been proven in Fraunhofer IVV. The Institute has also developed relevant processes.
wax dispersions are suitable for industrial processes
finely distributed particles are formed by wax by melting emulsification. Various emulsions are commercially available for stabilizing waxes. The emulsifying agent mixtures of Tween 20 and Span 20 produce a more stable dispersion than the mixtures of Twain 80 and Span 80. Condensation and convergence were not observed during the 21-day storage period. Wax dispersions are stabilized in such a way that they are suitable for industrial processes. Results and methods are also used to stabilize other wax dispersions and can be used in industrial applications.
the study was published in: Coatings 2018, Vol. 8, Issue 12, p. 469.
