PEN application fields continue to expand, and the industry has broad room for development

Polyethylene naphthalate (PEN) is a thermoplastic polyester with excellent properties and a new type of special engineering rubber material. PEN is an excellent polyester formed by the condensation polymerization of 2,6-naphthalenedicarboxylic acid dimethyl ester (NDC) or 2,6-naphthalenedicarboxylic acid (NDA) and ethylene glycol (EG). Compared with the traditional material PET, PEN has higher gas barrier properties, physical and mechanical properties, UV resistance, strong rigidity, radiation resistance, stable mechanical properties and other properties. It is widely used in electronic appliances, acousto-optic carriers, packaging materials, engineering materials, and films. It is widely used in fields such as materials and information recording materials.

The chemical structure of PEN is similar to that of PET. The biggest difference lies in the composition of the molecular chains of the two. There is a naphthalene ring in the molecular chain of PEN, and a benzene ring in the molecular chain of PET. The naphthalene ring structure makes PEN have higher physical and mechanical properties and gas barrier than PET. performance, chemical stability and other properties, so PEN is more suitable for industrial yarn than PET. PEN can not only be used as daily packaging materials, but also is a new type of special engineering rubber material. As the application fields of PEN gradually expand, the performance advantages of PEN become increasingly prominent. Enterprises related to my country’s PEN industry should continue to increase their independent research and development innovation capabilities and establish independent PEN production line with intellectual property rights to improve the company’s own competitiveness. Overall, PEN has huge market application potential in my country and broad room for industry development.

According to the “2020-2025 Polyethylene Naphthalate (PEN) Industry Market In-depth Research and Investment Prospects Forecast Analysis Report》shows that PEN has a wide range of uses and has great market application potential. From a global perspective, the world’s well-known large film production companies have entered the field of PEN film production, such as Toyobo. In terms of PEN materials, only Japan’s Teijin Group has the production capacity in the world, and it has now achieved large-scale production and supply. .

In the early days, the United States, Europe and Japan were the main suppliers of PEN in the world. Later, with the development of the market, European and American companies gradually withdrew from the market, and Japan became the only production region in the world. The current global PEN industry production capacity is around 10,000 tons, and my country’s demand for PEN and related products mainly relies on imports. Although there are many domestic enterprises and institutions that have conducted a lot of research on PEN products, such as China Packaging Industry Corporation, Yizheng Chemical Fiber Co., Ltd., Guilin Electrical Equipment Research Institute, etc., due to the fact that there are many substitutes for PEN products, the research and development innovation of relevant enterprises The enthusiasm needs to be improved.

Industry analysts said that compared with the traditional material PET, PEN has better performance, so the market demand is higher, but my country’s PEN The demand for and related products mainly relies on imports. From this point of view, my country’s PEN market has huge application potential. As the application fields of PEN gradually expand, enterprises related to my country’s PEN industry should continue to increase their independent innovation capabilities and establish PEN production lines with independent intellectual property rights. Overall, the PEN industry has broad development space.
