T306 is a high-performance amphoteric polyacrylamide dry-strength agent specifically developed for industrial papermaking applications, including packaging paper such as corrugated paper, kraft paper, and bobbin fibre paper, as well as cultural paper and various specialty papers. The agent’s reticular macromolecular structure incorporates both anionic and cationic functional groups, which are generally anionic, providing superior anti-interference performance against foreign ions commonly found in recycled or impure fibers.

By integrating T306 into the papermaking process, manufacturers can achieve significant improvements in dry strength, tensile strength, bursting resistance, ring crush strength, and interlayer adhesion of paperboard and packaging paper. Its unique amphoteric structure offers advantages over linear polyacrylamide dry-strength agents, including enhanced bonding between fibers, better sheet formation, and higher mechanical integrity of the final product.

T306 is particularly valuable for producers using recycled fibers or lower-cost pulp, as it allows a higher proportion of secondary fibers without compromising paper quality. The chemical improves fiber utilization efficiency while maintaining consistent physical properties such as strength, durability, and stiffness. Its high compatibility with other papermaking additives, including retention aids, drainage aids, and fillers, makes T306 ideal for integration into modern industrial papermaking lines, ensuring optimized production performance and cost savings.

In addition to packaging applications, T306 can be applied in cultural and specialty paper production, enhancing paper’s dry strength and maintaining sheet integrity during printing, folding, and converting processes. By improving tensile and bursting properties, T306 helps manufacturers meet the international quality standards required for global markets. Its reliability under various process conditions, including variable pH, water hardness, and fiber types, ensures stable performance, supporting high-volume production and sustainable paper manufacturing.
