PA6T (polyamide 6T) is a high-performance engineering plastic, widely used in the field of chemical production raw materials. Its upstream and downstream related products mainly include hexamethylene diamine, terephthalic acid, PA6, PA66 and so on.

1. Upstream related products

(1) Hexamethylene diamine

Hexamethylene diamine is one of the main raw materials for PA6T production, which is produced by the reaction of adipic acid and ammonia. The market price fluctuation of hexamethylene diamine has a great influence on the production cost of PA6T.

(2) Terephthalic acid

Terephthalic acid is another important raw material for PA6T production, which is mainly produced by the oxidation of p-xylene, a petroleum cracking product. The market supply of terephthalic acid also has a great influence on the production of PA6T.

2. Downstream related products

(1)PA6

PA6 is a commonly used engineering plastic, which has certain similarities with PA6T in structure and properties. PA6T can replace part of PA6 used in high temperature, high strength and other demanding areas.

(2)PA66

PA66 is also a common engineering plastic with high strength and toughness. PA6T and PA66 in some application areas there is a competitive relationship, but in some high temperature, chemical resistance and other areas of higher requirements, PA6T has more superior performance.

In addition, PA6T can also be modified with other polymers such as blending and reinforcement to generate more types of chemicals to meet the needs of different fields.

In short, PA6T has a wide range of application prospects in the field of chemical production raw materials, and its upstream and downstream related products involve many fields, which plays an important role in promoting the development of the chemical industry.
