Material Grades

Which PEEK grade should you choose?

PEEK is available in unfilled and reinforced formulations. The right grade depends on mechanical loading, wear conditions, dimensional requirements and electrical properties.

Virgin PEEK

Unfilled PEEK offers a balanced combination of mechanical strength, toughness, chemical resistance and temperature performance.

  • Good overall mechanical performance
  • High chemical resistance in many environments
  • Suitable for a wide range of machined parts
  • Useful where toughness is important

Carbon Fiber Reinforced PEEK

Carbon fiber reinforced PEEK is often selected when higher stiffness, improved load-bearing capability and dimensional stability are required.

  • Higher stiffness than unfilled grades
  • Potentially improved wear performance
  • Lower thermal expansion in suitable formulations
  • Electrical conductivity may be higher

Glass Fiber Reinforced PEEK

Glass fiber reinforced PEEK can provide increased stiffness and reduced thermal expansion for selected structural and dimensional applications.

  • Higher stiffness than unfilled PEEK
  • Improved dimensional stability in suitable designs
  • Useful for structural components
  • Wear and surface behavior depend on the formulation

Note: Reinforced PEEK properties vary with fiber content, fiber orientation, manufacturing process and supplier formulation. Confirm the specific grade data before final material selection.

Technical Data

Typical mechanical & thermal properties of PEEK.

The following figures are indicative reference values for unfilled virgin PEEK. Actual values depend on the grade, processing method, specimen preparation and test conditions.

Property Typical Reference Value Test Method / Notes
Density Approx. 1.30 g/cm³ ISO 1183
Tensile Strength Approx. 90–100 MPa ISO 527
Flexural Modulus Approx. 4.0–4.1 GPa ISO 178
Glass Transition Temperature (Tg) Approx. 143°C DSC
Melting Temperature (Tm) Approx. 343°C DSC
Continuous Use Temperature Often referenced around 250°C Depends on grade, load and environment

These figures are not guaranteed design values or product specifications. For engineering calculations, request the technical data sheet for the exact PEEK grade being considered. Filled grades may have significantly different mechanical, thermal, electrical and tribological properties.

Industry Applications

Where PEEK is used.

PEEK is selected for components that require a combination of temperature resistance, mechanical performance, chemical resistance and dimensional reliability.

Semiconductor & Electronics

PEEK may be used in wafer-handling components, equipment fixtures, insulation parts and selected fluid-handling components. Grade purity, particle generation and chemical compatibility should be evaluated for each process.

Oil & Gas

PEEK grades are used in selected seals, back-up rings, valve components and electrical connectors. Pressure, temperature, fluid compatibility and sour-service requirements must be checked against the specific grade.

Medical & Healthcare Equipment

Selected PEEK grades are used in medical equipment, surgical instrument components and other healthcare applications. Implant applications require specifically qualified medical or implant-grade materials and appropriate regulatory documentation.

Aerospace & Transportation

PEEK can be considered for lightweight structural parts, electrical components, clips and precision components where temperature and mechanical performance are important.

Industrial Machinery

PEEK is used in selected bearings, bushings, gears, wear strips and machine components. Grade selection should consider load, speed, lubrication and operating temperature.

Chemical Processing

PEEK offers resistance to many chemicals and can be used in selected pump, valve, sealing and fluid-handling components. Compatibility should be confirmed for the actual chemical concentration and operating conditions.

Material Selection

How to choose the right PEEK material.

Selecting PEEK is not only about temperature resistance. The operating environment and component design are equally important.

1. Operating temperature

Identify the normal operating temperature, peak temperature, exposure duration and mechanical load. PEEK's high-temperature capability does not mean every grade can maintain the same mechanical performance under every condition.

2. Mechanical load and stiffness

For components requiring higher stiffness or load-bearing performance, carbon fiber or glass fiber reinforced grades may be considered. For applications requiring greater toughness, unfilled PEEK may be more suitable.

3. Wear and friction requirements

For bearings, bushings and sliding components, consider contact pressure, sliding speed, lubrication, mating surface and operating temperature. Bearing-grade PEEK formulations vary, so review the supplier's grade-specific data.

4. Chemical exposure

Check the chemical type, concentration, temperature and exposure time. PEEK resists many chemicals, but compatibility should be confirmed for the actual service environment.

5. Manufacturing process

Choose the appropriate form according to your production method: granules for suitable melt processing, powder for compatible powder-based processes, sheet and rod for machining, and film for thin-section applications.

6. Dimensional and inspection requirements

For CNC components, provide drawings, critical dimensions, tolerances, surface finish requirements and inspection criteria. Achievable tolerances depend on geometry, material grade, dimensions and machining conditions.

Frequently Asked Questions

PEEK material FAQs.

Common questions about PEEK grades, forms, performance and material selection.

What is PEEK material?

PEEK stands for Polyetheretherketone. It is a high-performance semi-crystalline thermoplastic known for its mechanical strength, thermal performance, wear resistance and chemical resistance. It is used in demanding industrial and engineering applications.

What is the maximum operating temperature of PEEK?

Unfilled PEEK is commonly associated with continuous-use temperatures around 250°C. Actual performance depends on the material grade, mechanical load, environment and exposure duration. Always check the technical data for the selected grade.

What is the difference between virgin PEEK, CF30 PEEK and GF30 PEEK?

Virgin PEEK is unfilled and offers a balanced property profile. CF30 PEEK contains carbon fiber reinforcement and is generally selected for higher stiffness and dimensional stability. GF30 PEEK contains glass fiber reinforcement and can provide increased stiffness. The exact properties depend on the formulation.

Can PEEK replace metal components?

In selected applications, PEEK can replace metal where weight reduction, corrosion resistance, electrical insulation or reduced friction is important. However, the suitability depends on load, temperature, wear, creep and component design. Engineering evaluation is recommended before substitution.

Can you supply PEEK parts according to drawings?

Custom CNC machined PEEK parts can be discussed based on customer drawings and specifications. Please provide the drawing, material grade, quantity, critical tolerances and inspection requirements for evaluation.

Is all PEEK suitable for medical implants?

No. General industrial PEEK should not automatically be considered suitable for implant applications. Medical and implant uses require specifically qualified materials, appropriate documentation and compliance with the relevant regulatory requirements.

What information should I provide when requesting a PEEK quotation?

Please specify the product form, material grade, dimensions, quantity and intended application. For CNC parts, include drawings and tolerance requirements. For powder or granules, include the intended processing method and any relevant material specifications.
