POLYSTRON - Internal Strengthening Agent
Internal Strengthening Agent
POLYSTRON – Adding pulp slurry will improve paper strength. Used for a wide range of applications ranging from acid-to-weak acid papers, neutral papers, paperboards (e.g. liner, corrugating medium and core paper), fine papers and coat papers. Improves yield and drainage while increasing the internal strength, surface strength, and interlayer strength of paper.
Feature

- Achieves the same strength as starch with only about 1/3 to 1/4 of the additive amount.
- Improve production efficiency.
- Drying performance, papermaking speed.
- Reduce environmental load.
- Reduce COD and BOD
