The market size of polyethylene naphthalate (PEN) continues to expand, and there is an urgent need for localization.

Polyethylene naphthalate (PEN) is one of the important members of the polyester family. It is composed of 2,6-dimethyl naphthalate (NDC) or 2,6-naphthalenedicarboxylic acid (2,6-NDA). ) and ethylene glycol (EG), which is an emerging excellent polymer. Its chemical structure is similar to that of PET, except that the molecular chain of PEN is replaced by a more rigid naphthalene ring for the benzene ring in PET. The naphthalene ring structure gives PEN higher physical and mechanical properties, gas barrier properties, chemical stability, heat resistance, ultraviolet resistance, radiation resistance and other properties. It can be widely used in food packaging, medical containers, cosmetic packaging, electrical insulation materials, etc. .

The polyethylene naphthalate (PEN) industry is a technology-intensive industry with high entry barriers. At present, there are few companies with patented technology and production capabilities for polyethylene naphthalate (PEN) globally, and all of them are foreign companies. Especially the production capacity of polyethylene naphthalate (PEN) is controlled by In the hands of the Japanese emperor. Demand users in various countries, such as Toyobo, which produces polyethylene naphthalate (PEN) films, purchase polyethylene naphthalate (PEN) products from Japan’s Teijin Company and then produce polyethylene naphthalate. Polyethylene naphthalate (PEN) downstream products, so the polyethylene naphthalate (PEN) industry is highly concentrated. According to the released “2020-2025 Polyethylene Naphthalate (PEN) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report》 shows that in 2020, the global production of polyethylene naphthalate (PEN) will be only a few thousand tons. In China, due to the complex production process and high production cost of polyethylene naphthalate (PEN), there has been no domestic production equipment. Therefore, the supply of polyethylene naphthalate (PEN) in my country is basically blank, and the product is completely Rely on imports to meet domestic market demand in electrical insulation materials, food, medicine and other fields.

Polyethylene naphthalate (PEN) is a special engineering plastic. Compared with traditional materials, it has higher heat resistance, mechanical properties, and gas barrier properties, and has broad application prospects. However, due to its high production cost, The price/performance ratio is lower than alternative products such as PET, and its actual application scale is relatively limited. In recent years, as PEN manufacturers have increased their efforts to promote PEN products and the PEN downstream industry has transformed and upgraded, the application of polyethylene naphthalate (PEN) in the domestic market has gradually increased, and the future development prospects of the industry are good.

Analysts believe that at this stage, my country’s polyethylene naphthalate (PEN) industry is in the introduction stage, and is incompatible with the United States, Compared with developed countries such as Japan, our country’s technical level lags behind and there is a lack of professional and technical talents in the industry. Since domestic polyethylene naphthalate (PEN) is completely dependent on overseas imports, the recent Sino-US and Sino-Japanese trade frictions have posed huge potential risks to product import trade, and there is an urgent need for localization. To this end, relevant units in the polyethylene naphthalate (PEN) industry should improve their innovation capabilities and achieve localization of products as soon as possible through measures such as talent introduction, innovation team building, and technological innovation incentives.
