Uses:
1. Most of caprolactam is used to produce polycaprolactam, of which about 90% is used to produce synthetic fibers, namely capron, and 10% is used as plastics for manufacturing gears, bearings, pipes, medical equipment, electrical and insulating materials, etc. It is also used in coatings, plasticizers and a small amount of lysine synthesis.
2. Mainly used to prepare caprolactam resins, fibers and artificial leather, etc., and also used as a polymer solvent for pharmaceutical raw materials, to manufacture polyamide synthetic fibers, and gas chromatography stationary liquid.
