As a high-performance fiber, the polyetheretherketone fiber (PEEK fiber) industry has huge room for development

Polyetheretherketone fiber, also known as PEEK fiber, refers to a thermoplastic fiber whose main molecular chain contains phenylene etheretherketone links. Polyetheretherketone fiber is a fully aromatic fiber with the advantages of high strength, high temperature resistance, corrosion resistance, and creep resistance. It is widely used in composite materials, filter materials, military materials, aerospace, energy industry and other fields.

The main raw material of polyetheretherketone fiber is polyetheretherketone (PEEK), which is a thermoplastic engineering plastic. Polyetheretherketone has the characteristics of easy processing and creep resistance, and is widely used in many fields. Polyetheretherketone is a cutting-edge material with high technical barriers to the industry. There are only a small number of companies in my country with large-scale production capabilities for polyetheretherketone. In the future, with in-depth research and technological advancement, my country’s polyether ether ketone production capacity and quality will continue to improve, which will drive the rapid development of the polyether ether ketone fiber industry.

Polyetheretherketone fiber is usually divided into two types: multifilament and monofilament. Multifilament is composed of multiple single fibers, with a breaking strength of 65cN/tex. It is usually prepared by ordinary melt spinning method and can be used as a reinforcing agent for composite materials. The single fiber is spun with a single-hole spinneret and has a breaking strength The strength reaches 25~40cN/tex and can be used as filter material. As the market demand for segmented products continues to grow, the prosperity of the polyether ether ketone fiber industry continues to increase.

In 2022, the Ministry of Industry and Information Technology and the National Development and Reform Commission issued the “Guiding Opinions on the High-Quality Development of the Chemical Fiber Industry”, which clearly proposed to improve the production and application level of high-performance fibers and break through key purification and spinning technologies such as polyetheretherketone fibers. Benefiting from national policy support, my country’s polyether ether ketone fiber technology level will continue to improve.

According to the “2023-2028 China polyetheretherketone fiber (PEEK fiber) industry market in-depth research and development prospect forecast report》shows that polyetheretherketone fiber has a wide range of applications, including composite materials, filter materials, military materials, aerospace, energy industry, etc. In the field of military materials, polyetheretherketone fiber can be used to produce military clothing, tents, etc.; in the aerospace field, polyetheretherketone fiber can be used to produce aerospace high-performance wire and cable protective covers.

The main global manufacturers of polyether ether ketone fiber include Sumitomo Chemical Co., Ltd. of Japan, Solvay Group of Belgium, and Victrex of the United Kingdom. my country’s leading polyetheretherketone fiber enterprise is Jilin Zhongyan Polymer Materials Co., Ltd., which took the lead in realizing large-scale production of polyetheretherketone fiber in 2017.

Industry analysts said that as a high-performance fiber, polyether ether ketone fiber has good application prospects. The polyether ether ketone fiber industry has high technical barriers. After years of development, Chinese companies have developed large-scale production capabilities for polyether ether ketone fiber. With the continuous improvement of technological innovation level and national policy support, the output and quality of my country’s polyether ether ketone fiber will be greatly improved. Overall, there is still huge room for development in the polyetheretherketone fiber industry in the future.
