Polyamide PA66 has broad market prospects and industry development is limited by adiponitrile technology

Polyamide PA66 is a polyamide thermoplastic resin, commonly known as nylon-66. It is translucent or opaque and milky white. It is produced through the polycondensation reaction of oxalic acid and ethylenediamine. It has high tensile strength and good drug resistance. , good self-lubricating properties, earthquake resistance, self-extinguishing, low temperature resistance, corrosion resistance, wear resistance, impact resistance and other advantages, it is widely used in electronic appliances, automobiles, machinery, chemical industry and other fields.
The upstream of the polyamide PA66 industrial chain includes production raw materials and production equipment such as adipic acid, hexamethylenediamine, and additives. The midstream of the industrial chain includes the production of polyamide PA66. The downstream of the industrial chain includes application fields such as machinery, automobiles, electronics, and chemicals.
According to the“China Polyamide PA66 Product Market Analysis Feasibility Research Report 2023-2027” released by the Industrial Research Center, from the industry Analyzing the upstream chain, adipic acid and hexamethylenediamine are the direct raw materials for the production of polyamide PA66. Among them, adipic acid is mainly produced from pure benzene. my country’s production technology is relatively mature and the supply is sufficient. Hexamethylenediamine is mainly produced with adiponitrile as raw material. The technical barriers to adiponitrile production are high. The technical level of domestic enterprises is not enough to support the large-scale production of adiponitrile. The supply of adiponitrile is monopolized in the hands of a few foreign-funded enterprises. The domestic market demand is external. High degree of dependence. Due to the unstable supply of hexamethylenediamine raw materials, it is not conducive to the development of my country’s polyamide PA66 industry.
In recent years, in order to break the current situation of domestic adiponitrile production, many companies in my country have entered into the layout and strive to break through the technical barriers of adiponitrile. At this stage, certain progress has been made, and my country’s independent supply capacity of adiponitrile is expected to be enhanced. In addition, my country has a large output of polyamide PA66 and has become the world’s largest adiponitrile-polyamide PA66 market, attracting foreign giant adiponitrile companies to settle in China. At present, the world’s two largest adiponitrile manufacturers, Invista and Ascend, have invested in and built factories in Shanghai and Lianyungang respectively. Against this background, my country’s polyamide PA66 industry has promising development prospects.
From the downstream analysis of the industrial chain, engineering plastics have excellent comprehensive properties, with the advantages of high tensile strength, oil resistance, wear resistance, impact resistance, and good electrical insulation. They are the main application areas of polyamide PA66, accounting for approximately 10% of polyamide PA66 consumption. 60% of the total volume is mainly used in automotive parts, electronic and electrical fields. my country is the world’s largest automobile producer and a major automobile consumer. Its strong demand for engineering plastics will drive the growth in demand for polyamide PA66 and promote the rapid development of the polyamide PA66 industry.
Industry analysts said that at present, my country’s polyamide PA66 industry is highly concentrated, with Shenma, Huafeng Chemical, and Longhua New Enterprises such as Xinli New Materials, Xingjia Chemical, Youxiang Technology, and Dikai Industry are industry leaders. Among them, Shenma Co., Ltd., Huafeng Chemical, and Xingjia Chemical have a relatively high production capacity, accounting for about 50% of my country’s total polyamide PA66 production capacity. From the perspective of geographical distribution, my country’s polyamide PA66 companies are mainly distributed in the eastern coastal areas, among which Guangdong, Zhejiang, and Shanghai have more companies.
