Did you know that Nylon production depends heavily on ion exchange resins?
Nylon is a part of our everyday life. It is used in many industries such as textiles, carpeting and even in food packaging because of its temperature resistance for boil-in-the-bag food packaging.
Nylon is a polymer that uses adipic acid in its production. About 60% of the 2.5 billion kg of adipic acid produced annually is used for the production of Nylon. Adipic acid relies on copper and vanadium catalysts for its production, which can remain within the acid. However, for nylon polymerization to occur properly, it is critical that adipic acid is in its purest form. The removal of copper and vanadium is done by a robust, oxidant resistant cation exchange resin that can remove copper and vanadium while withstanding the harsh chemical environment of the adipic acid. The copper and vanadium can also be recovered from the cation resin to improve the economics of the process.
