PETER GREVEN – Your partner for paper additives

For application in the paper industry, we distinguish between two areas:

Paper Coating: product line LIGAFLUID®

In the coating of paper, our products are used as coating colour lubrication agents. High processing speeds with the production of coated papers and the demand for a failure-free process, also places equal demands on the materials used. Therefore, we have developed our soaps and metallic soaps to specialty products for these applications and have realised the following benefits:

  • The processing operations during and after coating are made easier.
  • Bonding of the colour coating on the upper calender roller is prevented.
  • The soaps and metallic soaps act as water repellents and reduce foam formation.
  • Gloss and smoothness of the coated papers are improved.

 

Deinking: product line SERFAX®

The extraction of pulp from waste paper is still significant. During the processing of the pulp the focus is put on saving natural resources and avoiding too much pressure on the environment. In addition, efforts can be seen to make the deinking process more environmentally friendly.

Collector chemicals based on soap make an important contribution, as the calcium soaps formed in the deinking process are physiologically safe and environmentally neutral. Following these trends also increases demands on the quality of the deinked pulp, and therefore the demands on the materials used. In addition to the degree of whiteness, today, ash discharge, reduction of pits and stickies with minimum fibre loss, play a major role.
