Caprolactam is created by a complex polymerization process using three major raw materials: sulfur, ammonia and cyclohexane. In an intermediate step, sulfur is modified to sulfuric acid liquid; ammonia is processed into hydroxylamine and cyclohexane is altered into cyclohexanone. These three chemicals combine to create two products, the first being
Caprolactam. The second, Ammonium Sulfate, is a co-product representing three quarters of the output of polymerization and is one of the key fertilizers used in Thailand. Caprolactam's main use is as the raw material for the production of Nylon 6 which consequently forms an integral part in a myriad of other consumer and industrial products, particularly for the automobile industry.
