Polyphenylene ether (PPO) has a wide range of applications and domestic enterprises have enhanced independent production capabilities

Polyphenylene ether (PPO for short) is a general-purpose thermoplastic engineering plastic and the most consumed variety among engineering plastic alloys. Polyphenylene ether appears as white particles and has excellent heat resistance, flame retardancy, dimensional stability, electrical insulation, etc. It is widely used in automobiles, photovoltaics, chemicals, water treatment, electronic appliances, medical equipment and other fields, among which electronic Electrical appliances are the main application scenario, accounting for more than 70% of applications.

Polyphenylene ether has excellent properties, is non-toxic and transparent, and can be processed by extrusion, blow molding, molding, injection molding, foaming, vacuum coating and other processing techniques. However, pure polyphenylene ether has poor melt fluidity and is difficult to process, so polyphenylene ether on the market has poor melt fluidity and is difficult to process. Phenyl ether is mostly modified polyphenylene ether (MPPO). The main varieties of modified polyphenylene ether include PPO/PS, PPO/PBT/elastomer alloy, PPO/PA/elastomer, etc. Domestically, Kingfa Technology’s modified polyphenylene ether has advanced technology and the most complete product system.

According to the “2022-2026 China Polyphenylene Ether Industry Brand Market Structure and Competitor Field Investigation Report released by the Industrial Research Center , polyphenylene ether has a wide range of application fields. In recent years, the global market has maintained a growth trend. In 2021, the global polyphenylene ether market will reach US$1.14 billion. It is expected that from 2022 to 2026, the global polyphenylene ether market will maintain an annual growth rate of more than 9.5%. average compound growth rate. Globally, the polyphenylene ether market is mainly distributed in North America and Europe, with the two regions accounting for approximately 50.0% of the market.

The production process of polyphenylene ether includes homogeneous solution polycondensation method and precipitation polycondensation method. Among them, homogeneous solution polycondensation method is the mainstream process. The polyphenylene ether production process is complex and the process is long. Due to technical limitations, there are few companies in the world with a production capacity of 10,000 tons of polyphenylene ether, mainly including Japan’s Mitsubishi Gas Chemicals, Asahi Kasei, Nantong Xingchen, Saudi Basic Industries, Xinbaoxin Among them, Nantong Xingchen is the only company in the world that masters two polyphenylene ether production processes at the same time, with a polyphenylene ether production capacity of 50,000 tons per year.

In recent years, with the development of the national economy, my country’s apparent consumption of polyphenylene ether has shown a fluctuating growth trend, reaching 28,000 tons in 2021. Compared with developed countries such as Europe and the United States, my country’s polyphenylene ether industry started late, and the market is still in the development stage. my country’s polyphenylene ether demand has long relied on imports. However, with technological breakthroughs and policy support, my country’s polyphenylene ether production capacity and independent supply have improved. Capabilities are constantly improving, and the pace of domestic substitution of polyphenylene ether is accelerating.

Industry analysts said that polyphenylene ether has wide application fields and huge market consumption. With the development of my country’s economy, the polyphenylene ether market Demand continues to be released, and the industry has certain room for development in the future. The production process of polyphenylene ether is complex. For a long time, my country’s demand for polyphenylene ether has relied on imports. However, in recent years, with favorable national policies and technological breakthroughs, the localization rate of polyphenylene ether has been continuously increasing, and the development of the industry will continue to improve.
