Internal paper strengthening agent [Polystron]

Adding this agent to the pulp slurry will strengthen the paper.

This agent can be used widely for acid-to-weak acid papers, neutral papers, paperboards (e.g., liner, corrugating medium and core paper), fine papers and coat papers. Adding this agent to the pulp slurry will improve the internal, surface and layer-to-layer interface strength of various papers or paperboards. It will also improve wet-end retention and inlet freeness as well.
