Another New Player Joins the PEEK Track! Why Is "Industrial Gold" So Highly Sought After?

A new player joins the PEEK track!

Polyether ether ketone (PEEK), belonging to the polyaryletherketone (PAEK) family, is a crystalline aromatic thermoplastic polymer composed of phenylene rings connected by ether and carbonyl linkages.

PEEK, due to its excellent mechanical properties, high heat resistance, and corrosion resistance, is also known as the "pinnacle of high-end engineering plastics."

Compared to conventional metals, PEEK material can significantly reduce the weight while meeting the required strength, achieving lightweighting. Specifically, the tensile strength of PEEK is three times that of aluminum alloy and twice that of steel. The flexural modulus of PEEK is four times that of aluminum alloy and 1.5 times that of steel.

The requirements for lightweight, high strength, and high precision materials in humanoid robots align well with the properties of PEEK material. PEEK is used in components such as joints, bearings, and gears in humanoid robots.

Additionally, in special environments such as high temperature, high humidity, and chemical corrosion, PEEK materials exhibit outstanding chemical resistance and stability, significantly expanding the application scenarios of humanoid robots.

Carbon fiber reinforced PEEK can be used to manufacture drone frames, propellers, and engine components, as well as lightweight structural parts for low-altitude flying cars (such as seats, doors, and window frames). It can also be used to produce housings for sensors and control systems.

Medical and Health: PEEK is widely used in spinal surgery, joint replacement, and trauma repair due to its excellent biocompatibility, elasticity modulus similar to bone tissue, and good wear resistance.

Aerospace: Due to its lightweight and high-strength properties, PEEK material has become an ideal choice for manufacturing internal structural components of aircraft.

PEEK material has excellent wear resistance and corrosion resistance, and can withstand the high temperature, high pressure, and high-speed operating environment inside aero engines. Therefore, PEEK bearings and seals have been widely used in aero engines.

According to incomplete statistics, major domestic enterprises include Jida Special Plastics, Junhua Co., Zhongyan Co., Pengfulong, Kingfa Sci & Tech, Water Co., Nanjing Julong, Haoran Special Plastics, and Panjin Weiyingxing, among others.

In August this year, Jiangsu Junhua High Performance Specialty Engineering Plastics Co., Ltd. inaugurated its new intelligent factory, officially completing the project with an annual production capacity of 1,000 tons of polyether ether ketone (PEEK), 100 tons of polyimide (PI) materials and related products, and 10,000 sets of precision molds.

Shandong Junhao High-Performance Polymers Co., Ltd., a wholly-owned subsidiary of Junhua Co., Ltd., owns production facilities with an annual capacity of 2,500 tons of industrial-grade PEEK, 300 tons of medical-grade PEEK, and 600 tons of polyimide.

Zhongyan Co., Ltd. currently has a production capacity of 1,000 tons per year of polyether ether ketone (PEEK). The company's main products are resin-form PEEK, with a product system comprising 52 specifications and grades.

In addition, the company's "Annual Production of 5,000 Tons of Polyether Ether Ketone (PEEK) Deep Processing Series Products Comprehensive Plant (Phase II) Project" is progressing in an orderly manner.

Jida Special Plastics has an annual production capacity of 500 tons of polyether ether ketone (PEEK), 500 tons of polyether ether ketone ketone (PEEKK), 500 tons of polyether ketone (PEK), and 100 tons of polyethersulfone (PES) resins and their modified materials.

As a major producer of polyether ether ketone (PEEK) and one of the drafters of national standards, Pengfulong has overcome bottlenecks in synthetic chemical processes and key application technologies. Its holding subsidiary, Zhongju Bio, has completed over 20 clinical trials of medical-grade polyaryletherketone, achieving a breakthrough in domestic production.

In 2025, the second phase of the Pengfulong Advanced Polymer Materials Future Factory is set to commence production, with an annual production capacity of polyaryletherketone reaching 1,500 tons.

Watts Co., Ltd. possesses a complete industrial chain capability for PEEK, encompassing "polymerization, modification, and profile processing."

In May of this year, Chongqing Watt Zhicheng New Material Technology Co., Ltd., a wholly-owned subsidiary of Watt Co., Ltd., officially obtained the "Work Safety Permit," marking the commencement of formal production for the 20,000-ton-per-year LCP resin materials project (Phase I and II) and the 1,000-ton-per-year PAEK resin materials project (Phase I).
