Market Segment Paper Chemicals

Apart from traditional aluminium compounds we supply the paper industry a wide range of specialties which help paper manufacturers meet the highest quality standards with respect to paper quality and ecological safety.

Our research and application technology department continually improves existing products and processes and supports customers in the optimum application of products and the construction or purchase of dosing devices.

Our Product Range:

Wet strength agents - GILUTON ® for various fields of application, e.g. wallpapers, laminates, packaging, filter papers and tissues; all products are low in AOX, do not require declaration and meet the recommendations of the German health and veterinary authorities.

Surface sizing agents - PERGLUTIN® lead, among others, to increased pick resistance, reduced linting, better printability and less load on the water circuits.

Aluminium compounds
  • Aluminium sulphate (solid and liquid) for fixing the rosin size on the surface of paper fibres and reduction of trash.
  • Sodium aluminate (solid and liquid) for internal sizing, pH regulation, stabilizing of water circuits containing CaCO3 charged waste paper, as well as improved retention and backwater processing.
  • Aluminium formate – ALTRIFORM® for the manufacture of chlorine- and acid-free papers and as a retention agent for laminating grades.
  • Polyaluminium chloride – GILUFLOC® for precipitating and fixing rosin size and for improving the filler and fines retention in the neutral range with simultaneous reduction of anionic trash.
