Papermaking

1. Improve the strength of the paper: can effectively enhance the dry strength and wet strength of the paper, make the paper more durable, reduce the rupture and tear during use.

2. Good adhesion: It has a strong bonding effect on fibers and fillers, which helps to improve the evenness and structural stability of the paper.

3. Improve the surface performance of the paper: make the surface of the paper smoother and more delicate, improve the printing and writing performance of the paper.

4. Reinforced fiber retention rate: Help fibers and fine fillers to better retain in the paper, improve the utilization rate of pulp and reduce production costs.

5. Improve water resistance: Give the paper a certain water resistance, suitable for some paper varieties that have water resistance requirements.

6. Excellent film formation: A uniform film is formed on the surface of the paper to protect the paper and improve its physical properties.

7. Good compatibility with other auxiliaries: It can be used with a variety of papermaking auxiliaries to play a synergistic role and optimize the overall performance of paper.

8. Environmental advantages: Compared with some traditional auxiliaries, PVA is more biodegradable and has less impact on the environment.
