Semi-aromatic nylon has broad application prospects and my country’s market has great room for improvement

High temperature resistant nylon refers to PA engineering plastics with long-term use temperatures above 150°C. According to the main chain structure, high temperature resistant nylon can be divided into fully aromatic nylon and semi-aromatic nylon. Fully aromatic nylon has a high melting point and is unfavorable for processing and operation, which limits its application expansion. Due to the introduction of benzene rings, semi-aromatic nylon has better performance and has gradually become a research hotspot in the field of high-temperature resistant nylon.

Semi-aromatic nylon is produced by the polycondensation of aliphatic diamines or diacids and diacids or diamines with aromatic rings. Semi-aromatic nylon has the dual characteristics of aliphatic nylon and fully aromatic nylon, that is, it has excellent heat resistance, electrical insulation, dimensional stability, corrosion resistance, etc. Semi-aromatic nylon has excellent processability and can be processed into precision parts. It is widely used in automobiles, electronics and electrical, aerospace, machinery, optics, military industry, packaging, sports and other fields.

According to the “2023-2027 China Semi-aromatic Nylon Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center It shows that the research, production and application of semi-aromatic nylon in foreign markets started early. The relevant production companies mainly include Germany’s BASF, Japan’s Mitsui Chemicals, the Netherlands’ DSM, Japan’s Kuraray, DSM, DuPont, etc. Compared with foreign markets, my country’s semi-aromatic nylon research started late. After entering the 21st century, thanks to the improvement of research capabilities and progress in preparation technology, the development of my country’s semi-aromatic nylon market has accelerated, and localized production capabilities have continued to increase.

Semi-aromatic nylon can be divided into homopolymerized semi-aromatic nylon and copolymerized semi-aromatic nylon, among which homopolymerized semi-aromatic nylon occupies an important position. As research continues to deepen, the types of semi-aromatic nylon continue to increase, including PA4T, PA6T, PA9T, MXD6, PA10T, PA12T, etc. At this stage, my country’s semi-aromatic nylon-related manufacturing companies include Kingfa Technology, GCL New Materials, Qingdao Sanlibennuo, Zhejiang New Hutchison, Wison Group, Shanghai Jieshijie, Junheng Industrial, Kechuang Polymers, etc.

PA10T is a new type of semi-aromatic nylon and one of the few high-temperature nylon products in my country with independent production capabilities. The raw material for PA10T production is castor oil, which is a bio-based environmentally friendly material with excellent comprehensive performance and strong market competitiveness. my country has independent production capabilities for PA10T. Kingfa Technology is the only domestic mass-producer. At this stage, Kingfa Technology’s PA10T production capacity is above 10,000 tons.

Industry analysts said that semi-aromatic nylon is a high-temperature resistant nylon with excellent comprehensive properties. It is widely used in automobiles, electronics, aerospace and aerospace. Applications in other fields are becoming more and more widespread. In the future, with the development of downstream industries, the market demand for semi-aromatic nylon will continue to be released. my country’s research on semi-aromatic nylon started late, and there is still a certain gap compared with developed countries abroad in terms of technology, output, types and physical and chemical properties.
