Overview Sheet Forming Disintigration Dispursing Freeness Testing


Estanit offers the HAAGE sheet formers following the Rapid Köthen-principle, as well as equipment for standardized disintegration, dispursing, and vacuum drying. Our equipment for freeness testing of wood pulp, mechanical pulp, composites, and paper stock further demonstrate that we possess the necessary knowledge for the analysis of raw materials suitable for laboratories as well as the paper industry.

The outstanding performance ability of our new HAAGE sheet formers as well as the distinguished quality of its sheet formation and sheet drying have repeatedly been analyzed and validated by the Institute for Paper Technology of the University of Technology Darmstadt.
