Wet Strength Agents (WSAs) are a class of cationic, water-soluble polymers specifically designed to impart temporary or permanent resistance to rupture, disintegration, and bursting when paper and paperboard products are saturated with water. They are essential functional additives in the papermaking industry, enabling the production of grades that must maintain a significant portion of their dry strength under wet conditions.<\/p>\n
The core function is to significantly increase the\u00a0wet tensile strength,\u00a0wet burst strength, and, to a lesser extent,\u00a0wet stiffness\u00a0of paper products.
