Caprolactam is one of important organic chemical raw materials, it is mainly used to produce the polyamide chips (usually called nylon -6 slicing, slicing or nylon -6) through polymerization, which can be further processed into nylon fibers, engineering plastics, plastic film. Nylon -6 slice has different focuses in application field with different quality and index.

Applications:
Caprolactam is mainly used to produce poly caprolactam, 90% of which is for the production of synthetic fiber, namely polycarbonate, 10% is used in production of plastics, gear, bearing, pipe, medical equipment and electrical insulation materials, etc. It is also used in paint, plastic agent and a small amount of synthetic lysine etc.
It is mainly for preparing caprolactam resin, fiber and artificial leather, it is also used as pharmaceutical raw materials.
