Caprolactam
CAS Number: 105-60-2
Caprolactam is the cyclic amide monomer for nylon 6 (polyamide 6) production via ring-opening polymerization. It is one of the highest-volume polymer monomers globally, used to manufacture nylon 6 fibers, engineering plastics, films, and coatings. Caprolactam is available in fiber-grade and engineering-grade purities with stringent color and water specifications.
