T306 is an amphoteric polyacrylamide-based dry-strength agent designed for a wide range of industrial papermaking applications, including corrugated paper, kraft paper, bobbin fibre paper, cultural paper, and specialty paper. Its three-dimensional network structure, containing both anionic and cationic functional groups, delivers superior anti-ion interference properties, allowing the product to perform effectively even with high proportions of recycled fibers or variable pulp quality.

By using T306, papermakers can significantly enhance paperboard dry strength, tensile strength, bursting resistance, ring crush, and interlayer adhesion, outperforming traditional linear polyacrylamide-based dry-strength agents. The unique amphoteric design strengthens fiber bonding and improves sheet integrity, ensuring consistent mechanical properties and high-quality paper for both domestic and international standards.

T306 enables manufacturers to utilize economical raw materials or a higher percentage of recycled fibers without compromising paper performance, offering cost-effective solutions in large-scale papermaking operations. It is compatible with other papermaking chemicals, including retention aids, drainage aids, fillers, and wet-end additives, allowing seamless integration into modern industrial papermaking lines for optimized process efficiency.

In addition to packaging paper, T306 is ideal for cultural and specialty paper production, where maintaining dry strength and dimensional stability during printing, folding, and converting is critical. Its performance is stable under varying pH, water hardness, and fiber compositions, ensuring reliable results across different production environments. This makes T306 a versatile industrial papermaking additive that enhances paper strength, durability, and production efficiency while supporting sustainable fiber utilization.
