POLYGAL - Paper
With years of development work, we have adapted the most useful hydrocolloids from the galactomannan group, in particular guar gum, to the specific conditions of modern paper production. We use chemical modifications to develop high-quality additives that can be employed productively in pulp, in size presses and in coating formulations. With their low concentrations of use and quality advantages, our products are a competitive alternative to starch.
The POLYGAL brand includes a wide range of non-ionic, anionic and cationic galactomannan derivatives that offer useful effects when added at appropriate points in the production process.

For test runs, we can provide our own internally-developed compact and automated dissolving stations if necessary.
Our technical service is available to help you make sure to use the right product in the right place and in the optimal amount.
Our technicians may recommend circle studies or laboratory analyses in some situations. We can provide technical assistance for industrial trials upon request.
