A new player joins the PEEK track!

Fuchun Dyeing & Weaving:

New business focuses on downstream applications of PEEK

Not long ago, Fuchun Dyeing and Weaving invested in establishing a wholly-owned subsidiary, Wuhu Fuchun High-Tech Co., Ltd., focusing on the research, innovation, and industrialization of "industrial gold" PEEK.

It is reported that Fuchun Dyeing and Weaving is currently focusing on downstream applications of PEEK, such as semiconductors, medical devices, and lightweight solutions for humanoid robots. It will also actively explore applications in new energy vehicles and the low-altitude economy sectors.

Guoen Co., Ltd.:

The subsidiary plans to launch a PEEK materials project.

On August 1st, Guoen Co., Ltd. announced that it has completed the development of production technology and core processes for PEEK materials. The company plans to establish a fully integrated vertical platform covering the entire PEEK industry chain—from polymerization to compounding and final products—through its wholly-owned subsidiary, Zhejiang Guoen Chemical Co., Ltd. It also intends to build a pilot platform for styrene engineering material polymerization and launch a project for 300,000 tons/year of organic polymer modification and composite materials.

At present, the project has obtained the record-filing from the Economic Development Bureau of the Zhoushan High-tech Industrial Park Administrative Committee.

The total investment of the project is 960 million yuan, intending to build 2 PEEK polymerization production lines; 1 pilot-scale polymerization unit for styrene-based engineering materials; and 36 production lines for modified and composite materials.

What makes PEEK so attractive?

Why is it so popular?

This starts with PEEK's "all-around skills."

First, let's take a look at what PEEK is.

PEEK：

High-end engineering plastics at the pinnacle of the pyramid

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.

With the rapid development of emerging fields such as humanoid robots and the low-altitude economy, PEEK has emerged with its "full set of skills," and market demand is continuously rising.

Humanoid robot field

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.

Low-altitude economy sector

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.

Other Fields

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.

Zhongyan Co., Ltd. showcased medical implant-grade PEEK products at CHINAPLAS 2025.

Automotive: PEEK material can be used to manufacture lightweight components such as engine covers, bearings, brakes, ABS valves, and clutches.

Semiconductors: PEEK profiles for semiconductor manufacturing are specially treated to meet the specific requirements of semiconductor production processes, such as anti-static properties, low outgassing, and extremely high mechanical strength. They are mainly used in components such as CMP retaining rings, wafer carriers, and wafer chucks.

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.

Seeing these high-end and highly demanded applications, it is easy to understand why PEEK has become so popular.

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.
