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.
Advantage
-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.
Features
-Reduce the influence of filler on the binding force between fiber and fiber.
-Fiber with small particle size forms a micro-polymer itself.
