 Name: T302 Dry-strength agent

T302 Dry-Strength Agent is a high-performance papermaking chemical specifically designed for enhancing dry strength and overall physical properties of paper. Widely used in packaging paper, including corrugated paper, kraft paper, and bobbin paper, as well as cultural paper and specialty paper, T302 enables papermakers to maintain strong paper quality while incorporating low-cost fiber raw materials or a higher proportion of recycled fibers. This makes it ideal for cost-effective and sustainable paper production.

Formulated as a reticular-structured amphoteric polyacrylamide dry-strength agent, T302 contains both anionic and cationic functional groups in its macromolecular chains, predominantly cationic, providing excellent anti-foreign ion interference ability in complex pulp systems. Its networked molecular structure delivers superior reinforcement compared to traditional linear polyacrylamide dry-strength agents, effectively improving tensile strength, bursting strength, ring crush strength, and interlayer adhesion of board paper. Additionally, T302 supports excellent retention and drainage performance, ensuring smooth paper machine operation and consistent quality.

Thanks to its high stability and consistent performance under varying pulp conditions, T302 is particularly effective in high-speed papermaking machines and a wide range of paper grades. It provides a reliable dry-strength solution for corrugated board, kraft packaging paper, cultural paper, and specialty paper, helping manufacturers optimize both product durability and production efficiency. By integrating T302, companies can enhance paper machine runnability, improve recycled fiber utilization, and achieve cost-effective, high-performance paper production.
