PA66 (polyamide 66) is a synthetic polymer widely used in the field of chemical production. In the production process of PA66, the upstream related products mainly include raw materials such as adipic acid and hexamethylene diamine, while the downstream related products include various plastic products, fibers and films based on PA66.

1. upstream associated products

1. Adipic acid: Adipic acid is one of the main raw materials in the production of PA66, through the polycondensation reaction with hexamethylene diamine to produce PA66. Adipic acid production raw materials are mainly benzene, nitric acid and hydrogen.
2. hexamethylene diamine: hexamethylene diamine is also one of the main raw materials in the production of PA66, the same with adipic acid polycondensation reaction, the formation of PA66. The raw materials for the production of hexamethylene diamine are mainly adiponitrile, hydrogen and ammonia.

In addition, the production process of PA66 also needs some auxiliary raw materials, such as catalysts, antioxidants, etc., to ensure the smooth progress of the polymerization reaction and the quality of the product.

2. downstream related products

PA66 as a high-performance engineering plastics, with excellent heat resistance, wear resistance, impact resistance and dimensional stability, so it is widely used in various fields. The following are some of the main downstream related products of PA66:

1. Plastic products: PA66 can be used to produce various plastic products, such as auto parts, electrical accessories, industrial parts, pipes, valves, etc. These products have the advantages of high strength, high temperature resistance, corrosion resistance, etc., and can operate stably for a long time in harsh working environments.
2. Fiber: PA66 fiber has the advantages of high strength, high modulus, wear resistance, wrinkle resistance, etc., and is widely used in textiles, industrial textiles and reinforcing materials.
3. film: PA66 film has excellent heat resistance, oil resistance, puncture resistance and barrier properties, can be used for packaging food, pharmaceuticals, electronic products, etc.

In short, PA66 as an important chemical production raw materials, its upstream and downstream related products are widely used in various fields, for people's production and life has brought a lot of convenience.
