Polyarylate (PAR) has huge market potential and high technical barriers to the industry

​​ ​ ​ Polyarylate (PAR), also known as aromatic polyester, is made from polycondensation of dihydric phenols and dicarboxylic acids. It is a high-temperature resistant plastic with excellent comprehensive properties. Polyarylate has weather resistance, heat resistance, and impact resistance, and is widely used in electronic products, automobile manufacturing, household appliances, sports equipment, medical and health care and other fields.

The main synthesis processes of polyarylate include interfacial polycondensation method, melt polycondensation method and phase transfer catalytic method. The interfacial polycondensation method has the advantages of mild reaction conditions, high raw material utilization, fast reaction speed, low energy consumption, and green environmental protection. It is the mainstream synthesis process of polyarylate and has achieved industrial production; the melt polycondensation method refers to the raw material monomer and the resulting polymer. The phase transfer catalysis method is still in the laboratory stage and has not been developed yet. Achieve large-scale applications.

​​​​​Polyarylate is used in a wide range of applications, including electronic products, automobile manufacturing, household appliances and other fields. In the field of electronic products, polyarylate can be used to produce mobile phone cameras, watch casings and camera parts; in the field of automobile manufacturing, polyarylate can be used as inner lenses for direction lights, interior light lenses, rear light diffusers and other automotive lighting components. Components; in the field of household appliances, polyarylate can be used to produce light bulbs, grounded sockets and switches. In addition, with the continuous breakthroughs in production technology, polyarylate has also gained broad application prospects in high-tech fields such as ship stealth and bulletproof, aircraft engine anti-fragmentation, and military hovercraft.

Globally, the polyarylate market is mainly concentrated in Europe, the United States and Japan. Leading companies include Sumitomo Chemical Industries, Kuraray, Unitika, Celanese, DuPont, an American company, etc. Japan’s Unitika is the world’s first company to achieve industrialized production of polyarylate.

According to the “2022-2027 China Polyarylate (PAR) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that the technical barriers of the polyarylate industry are high, and overseas developed countries have implemented purchase restriction policies on my country, resulting in long-term high market prices. The main polyarylate manufacturers in my country include Harbin Polyarylate New Materials Co., Ltd., Shandong Kaisheng New Materials Co., Ltd., and Shanghai Jieshijie New Materials (Group) Co., Ltd. At present, my country’s polyarylate industry is still in the research and development stage, and the localization rate of products is low.

Industry analysts said that polyarylate, as a special polymer material, is expected to be widely used in high-tech fields such as aerospace and aerospace. . At present, due to factors such as high technical barriers, the development of my country’s polyarylate industry is slow, product quality and output are low, and it is unable to meet market demand. In the future, driven by technological innovation, the localization process of polyarylate in my country will be accelerated.
