Filler Strength

Adding fillers can reduce papermaking costs and improve functional properties such as appearance, smoothness, whiteness, opacity, etc. Therefore, increasing the filler content of paper has always been a goal pursued by paper and board manufacturers. However , an increase in fillers usually leads to a decrease in retention and paper strength. Our filler strength agent can reduce these negative effects by modifying the fillers.


-Improve the quality of the paper such as bonding strength, tensile strength.

-Increase the filler content while maintain strength and opacity of the paper.

-Improve filler retention, which is conductive to forming and drainage.

-Improve the whitewater circulation system.

-Improve drainage efficiency.



-Reduce the influence of filler on the binding force between fiber and fiber.

-Fiber with small particle size forms a micro-polymer itself.
