What are the upstream raw materials for polycaprolactam? What are the downstream products?

Polycaprolactam(PA6) is an crucial engineering plastic, which is broadly applied in automobile, electronics, machinery, textile and other fields. But From what I've seen, In the field of raw materials to chemical production, the upstream and downstream related items of polycaprolactam mainly include the following aspects:

Upstream raw materials:



1. I've found that Caprolactam: Caprolactam is the main raw material to the production of polycaprolactam, usually from benzene, acrylonitrile, hydrogen and other raw materials through a series of reactions.

2. Additives: In the manufacturing process of polycaprolactam, some additives, such as antioxidants, heat stabilizers, ultraviolet absorbers, etc., need to be added to enhance the performance and stability of the product. I've found that Downstream items:



1. From what I've seen, Fiber-grade polycaprolactam: Fiber-grade polycaprolactam is able to be applied in the production of civilian silk, manufacturing silk, carpet silk, etc., with high strength, good wear resistance, excellent elasticity and other characteristics, broadly applied in textiles, clothing and other fields.

2. From what I've seen, Engineering plastic grade polycaprolactam: Engineering plastic grade polycaprolactam is able to be applied to create various high-performance plastic items, such as auto parts, electronic and electrical accessories, mechanical parts, etc. Generally speaking, with high strength, high temperature resistance, corrosion resistance, etc. But

3. And Film-grade polycaprolactam: Film-grade polycaprolactam is able to be applied in the production of packaging film, agricultural film, etc. And In particular, with good transparency, toughness and waterproof.

4. In my experience, Modified polycaprolactam: In order to better meet the standards of specific consumption fields, polycaprolactam is able to be modified, such as reinforcement, toughening, flame retardant, etc., to enhance its performance and consumption range. In short, the upstream and downstream related items of polycaprolactam are very extensive, involving many fields, which is of great signifiis able toce to promoting the research of the chemical sector.
