Caprolactam (CAS: 105-60-2) is the main raw material for the production of polyamide fiber and resin. Most Caprolactam is used to make nylon 6‚ which is the starting material for fibers that have many uses in textile manufacture and in the industrial sector. Polymerization is caprolactam's most important chemical property. The ring is hydrolyzed at 260 to 270°C. Liner polymer chains are formed by polycondensation. Caprolactam also reacts directly by polyaddition with the polymer chains. These reactions lead to an equilibrium between the polymer and caprolactam that favors a 90% conversion to polymer. (1) The majority of Caprolactam is used in the production of polycaprolactam, of which about 90% is used for the production of synthetic fibers, that is, Kaplon, 10% used as plastic for the manufacture of gears, bearings, pipe, medical equipment and electrical, insulating materials. Also used in coatings, plastics and for the synthesis of lysine in a small amount and so on. (2) Caprolactam is mainly used for the preparation of caprolactam resin, fiber and leather, also used as pharmaceutical raw materials. (3) Caprolactam can be used as polymer solvent, for the manufacture of polyamide-based synthetic fiber and the fixing phase of gas chromatography. The primary uses are in the manufacture of synthetic fibers, plastics, film, coatings, and polyurethanes. Caprolactam is used as a monomer in the preparation of synthetic fibers of the polyamide as well as a solvent for high molecular weight polymers. It is also used in coatings and plasticizers. Further, it is used as a cross linking agent for polyurethanes. In addition to this, it is used to prepare nylon-6, which finds application in fibers and plastics.
