Brief IntroduBrief Introduction of Adipic Acid Application in Papermakingction of Adipic Acid Application in Papermaking

Adipic acid is the core synthetic raw material for PAE, an environmentally friendly wet strength agent in papermaking, and it is not added directly to pulp. After being chemically synthesized into PAE agent, it can cross-link with paper fibers to greatly improve the wet strength and water resistance of paper, and also assist in retention and drainage.It is mainly used for water-resistant paper grades such as paper cup base paper, food packaging paper and medical specialty paper. It can also modify papermaking coating materials to reduce paper dusting and poor surface strength, serving as a key raw material for formaldehyde-free papermaking additives.

Latest Industry NewsTechnology Upgrade: The industry develops low-chlorine PAE based on adipic acid to meet safety standards for food-grade paper and replace traditional high-chlorine additives.New Application Scenarios: Adipic acid modified nanocellulose is applied in new-energy paper-based separators, expanding new material fields for the papermaking industry.Cost Correlation: Price fluctuations of adipic acid directly affect the additive production costs of specialty paper and packaging paper.Testing Standards: Adipic acid traceability testing technology has been implemented in the industry to precisely control the quality of papermaking wet strength agents.
