The physical integrity of paper products, especially under moist conditions, is largely dependent on the chemical additives used during manufacturing. NINGBO INNO PHARMCHEM CO.,LTD. is a prominent supplier of advanced paper chemicals, with a strong focus on Polyamidoamine Epichlorohydrin (PAAE) resins, also known as PAE resins. These agents are indispensable for imparting superior wet strength, a critical property for a wide range of paper goods.

At its core, a wet strength agent works by creating a robust network of cross-linked fibers within the paper structure. This network resists the weakening effect of water on the hydrogen bonds that typically hold cellulose fibers together. PAE resins, being cationic thermosetting polymers, are particularly effective. Their chemical structure allows them to readily bind to the anionic sites on cellulose fibers. During the drying and curing process, these resins form covalent bonds, providing permanent wet strength that significantly enhances the paper's durability when wet.

The application of PAE resin is not without its technical considerations. Factors such as pulp freeness and kappa number play a role in how efficiently the resin is retained and activated. For instance, refining the pulp to a lower freeness can increase fiber surface area and negative charge, thereby improving PAE retention. However, extreme refining can lead to processing issues and affect recyclability. NINGBO INNO PHARMCHEM CO.,LTD. offers technical support to help clients optimize these parameters. When you choose to buy PAE resin from us, you gain access to expert advice on achieving the best performance for your specific papermaking needs.

The versatility of PAE resins is evident in their broad application spectrum. They are crucial for producing high-quality tissues, paper towels, and facial tissues. They also enhance the performance of packaging materials, ensuring they can withstand various environmental conditions, and are used in specialty papers like currency and filter papers. The development of new generations of PAE resins also addresses environmental concerns, offering reduced byproducts and improved sustainability profiles.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to advancing the field of paper chemistry. By providing high-performance PAE resins and expert technical support, we empower paper manufacturers to create products that meet the highest standards of quality, durability, and performance, while also embracing more sustainable manufacturing practices.
