In the field of advanced materials, polyetheretherketone (PEEK) sheets are reshaping the technical boundaries of multiple industries with their outstanding performance. Made of high-performance thermoplastic polymers, these sheets are ideal for extreme environments due to their high temperature resistance, corrosion resistance, and high strength. Their applications continue to expand from aerospace to medical equipment.

1. What is PEEK Sheet?

PEEK Sheet is a sheet material formed by melting PEEK resin.

As a semi-crystalline polymer, PEEK resin has a high melting point of 343℃. 

The processed sheet retains its core advantages:

1.It can work at 260℃ for a long time and withstand high temperature above 300℃ for a short time.

2.The tensile strength reaches 90MPa, with both rigidity and toughness.

3.It can resist corrosion from strong acids, strong alkalis and organic solvents.

4.It has excellent dimensional stability and is not easy to deform when the temperature changes drastically.

5.It is a revolutionary material that replaces metal and traditional plastics.

2. Cross-industry application scenarios

Aerospace field: manufacturing cabin interiors, engine components and cable insulation layers. The lightweight characteristics reduce the weight of aircraft by 5-10%, and can withstand extreme temperature differences at high altitudes.

Automotive industry: used in gearbox seals and brake systems to maintain sealing performance in the high temperature environment of the engine compartment and extend the maintenance cycle.

Medical and health field: PEEK plates that meet ISO 10993 biocompatibility standards are processed into spinal fusion devices and dental implant abutments. The elastic modulus is close to that of human bones, which can reduce stress shielding complications.

Electronics industry: Using its excellent insulation properties, semiconductor wafer carriers and 5G base station filter housings are made.

3. Performance showdown with traditional materials

Compared with stainless steel: 70% lighter, no need for anti-corrosion treatment, and 3-5 times longer service life in chemical equipment.

Compared with PTFE: The compressive strength is increased by 3 times and can be used for high-pressure valve gaskets.

Compared with epoxy resin composite materials: The upper temperature resistance limit is increased by 100℃, which is more suitable for the engine compartment environment.

Cost: The initial cost is high, but the life cycle cost is reduced by 20-30%, which is cost-effective in the field of high-end equipment.

4. Customization and market trends

Customization options:

Thickness: 0.1-50mm.

Reinforcement materials: Adding carbon fiber, glass fiber, etc. can increase the bending strength by up to 150%. Surface treatment: Sandblasting and coating can be performed to meet different friction coefficient requirements.

Market trends:

The global PEEK board market is growing at an average annual rate of 8.5%, especially in Asia.

Industry data: Demand in the aerospace field accounts for 35%, and the medical field has the fastest growth, with an annual growth rate of more than 12%.

5. Future development

With the advancement of Industry 4.0 and the upgrading of green manufacturing needs, the application of PEEK boards in emerging fields such as hydrogen energy equipment and deep-sea exploration is rapidly expanding. This material, which was born in the 1980s, is becoming an indispensable basic material for high-end manufacturing with its "plastic gold" characteristics, and is driving various industries to develop in a more efficient, reliable and environmentally friendly direction.
