PEEK Material
Unfilled and reinforced PEEK materials for precision parts that require strength, wear resistance and dimensional stability at elevated temperatures.
High-Performance PEEK for Demanding Components
PEEK, or polyether ether ketone, is a semi-crystalline engineering thermoplastic used in demanding mechanical, thermal and chemical environments. It combines high strength and stiffness with wear resistance, low moisture absorption and good dimensional stability.
Golden Collar supplies PEEK stock shapes and manufactures custom PEEK parts according to drawings. Available grades and dimensions should be confirmed for each project.
Key PEEK Properties
PEEK is selected when a component needs more mechanical, thermal or dimensional performance than conventional engineering plastics can provide.
Strength & Stiffness
PEEK maintains useful mechanical performance under demanding loads and at elevated temperatures.
Wear & Creep Resistance
Suitable grades support bearings, bushings, seals and components exposed to motion or long-term stress.
Dimensional Stability
Low moisture absorption and good resistance to deformation support close-tolerance components.
Chemical & Hydrolysis Resistance
PEEK resists many industrial chemicals, oils, fuels, steam and hot water. Check compatibility against actual service conditions.
Precision Machinability
PEEK can be CNC turned, milled and drilled into complex parts when grade, geometry and heat are properly controlled.
PEEK Grade Options
Select the PEEK grade around the finished component, operating conditions and required documentation.
| PEEK Grade | Key Characteristics | Typical Uses | Selection Note |
|---|---|---|---|
| Unfilled PEEK | Balanced strength, chemical resistance, electrical insulation and machinability | Insulators, valve parts, seals and precision components | General-purpose choice where reinforcement is not required |
| Glass-Filled PEEK | Higher stiffness, lower thermal expansion and improved dimensional stability | Structural and static-load components | Fiber reinforcement can affect machining and mating surfaces |
| Carbon-Filled PEEK | Higher stiffness, improved wear performance and greater thermal conductivity | Bearings, wear parts and mechanically loaded components | Electrical conductivity and tool wear should be considered |
| Bearing Grade PEEK | Formulated for lower friction and improved wear resistance | Bushings, guides, thrust washers and sliding components | Confirm filler system, load, speed and mating surface |
Final grade selection should consider temperature, load, movement, chemicals, electrical requirements and dimensional tolerances.

PEEK or PTFE?
Both materials perform in demanding environments, but they solve different engineering problems.
Strength & Dimensional Control
PEEK is generally selected when higher mechanical strength, stiffness, wear resistance and dimensional stability are required.
Low Friction & Chemical Inertness
PTFE is often preferred when very low friction, broad chemical inertness and electrical insulation are the main requirements.
PEEK Material FAQs
What is PEEK material?
PEEK is a high-performance semi-crystalline thermoplastic used for parts requiring strength, wear resistance, chemical resistance and dimensional stability at elevated temperatures.
What PEEK grades are available?
Common options include unfilled PEEK, glass-filled PEEK, carbon-filled PEEK and bearing-grade PEEK. Availability depends on the required form and dimensions.
Is PEEK easy to machine?
PEEK can be CNC turned, milled and drilled into accurate components. Reinforcement, heat generation, workholding and part geometry must be controlled during machining.
What is the difference between PEEK and PTFE?
PEEK normally provides higher strength and stiffness. PTFE provides lower friction and broader chemical inertness. The better choice depends on the component and its operating conditions.
What information is needed for a PEEK quotation?
Send the drawing or dimensions, quantity, required grade, tolerances, application and operating conditions. Include any inspection or documentation requirements.
