What is Polyetheretherketone Material

PEEK 450 CF30 black 9579 is a carbon fiber reinforced polyetheretherketone material developed by Ensinger of Germany. This material, with precision engineering and adaptation to extreme environments at its core, combines the inherent thermal stability of PEEK with the rigidity of carbon fiber, enabling it to demonstrate outstanding performance stability in structural components, load-bearing parts, and high-friction environments.

01 | Material Highlights and Characteristics

Carbon fiber enhances structural strength

  ・The approximately 30% carbon fiber content significantly enhances tensile strength and modulus, enabling the polyetheretherketone material to maintain dimensional stability and mechanical integrity even under high loads.

Excellent heat resistance

  ・It can be used for a long time at 260°C and can withstand short-term temperatures up to 300°C, meeting the extreme working conditions of automotive engine compartments, thermal mechanical devices and electronic insulation components.

Dimensional stability and low shrinkage rate

  ・After molding, the deformation rate is extremely low, making it suitable for high-precision assemblies and complex-shaped components.

Good wear resistance and self-lubricating performance

  ・The carbon fiber network forms a stable friction interface on the surface, reducing the wear rate and extending the service life of the parts.

Black appearance and high surface texture

  ・It provides visual uniformity and anti-pollution performance in industrial equipment or appearance parts, and is widely used in high-end commercial equipment.

02 | Typical Application Fields

  ・Automotive industry: High-temperature load-bearing components such as engine compartment brackets, clutch assemblies, oil pump parts, and turbine spacer rings.

  ・Mechanical engineering: Wear-resistant sliding rings, gears, bearing housings, sealing rings, etc.

  ・Electronic and commercial equipment: Printer rails, connector housings, electrostatic sensitive parts.

  ・Precision instrument engineering: Structural components requiring high rigidity and thermal stability in aviation and medical machinery.

This polyetheretherketone material performs particularly well in engineering applications that require extremely high dimensional accuracy due to its high specific modulus and extremely low coefficient of thermal expansion.
