Recent advances in silica nano-particle technology for papermaking.

Sweden / Швеция

Nanoparticle retention aid systems have been in commercial use for a quarter of a century now. This paper will review the development of these systems from the initial combination of starch and colloidal silica to the presents systems employing four or more components all with tailor-made functionality and nano-structure. Examples will be given on how nano-structure can be related to paper properties and paper machine performance.
