Material
PEEK
PEEK is a high-performance engineering thermoplastic used in demanding applications requiring mechanical strength, chemical resistance, and elevated-temperature performance. It is commonly selected for aerospace, medical technology, semiconductor equipment, and industrial components where conventional engineering plastics may not meet operating requirements.
Material overview
Polyether ether ketone (PEEK) is a semi-crystalline thermoplastic known for its high mechanical performance, chemical resistance, and ability to operate at elevated temperatures.
Material properties depend on grade, reinforcement, manufacturing process, and service conditions.
Common variants include:
- Unfilled PEEK: Suitable for precision components requiring balanced mechanical and chemical performance.
- Glass-filled PEEK: Used where increased stiffness and dimensional stability are important.
- Carbon-filled PEEK: Selected for applications requiring improved stiffness, wear performance, or specific thermal characteristics.
- Bearing-grade PEEK: Specialized formulations designed for sliding and wear-related applications.
Manufacturing methods include CNC milling, turning, injection molding, extrusion, and specialized processing.
Typical applications include high-temperature bushings, semiconductor equipment components, aerospace fittings, chemical processing parts, and precision mechanical assemblies.
PEEK machining requires attention to heat generation, workholding, residual stress, and dimensional stability.
Buyers should specify the exact material grade, reinforcement content, operating temperature, chemical exposure, dimensional tolerances, and quantity.
Regulated applications may require additional material documentation, biocompatibility evidence, or application-specific compliance verification.
Metraxio supports structured PEEK manufacturing RFQs for precision components and demanding industrial environments.
Buyer questions
Where do I put the PEEK compound?
In the manufacturing project. Unfilled, glass-filled and bearing grades behave differently, and the taxonomy keeps them under the PEEK material rather than as separate public grades.
Is PEEK usually machined?
Prototype and low-volume parts are commonly machined from stock. Injection molding exists for quantities that justify a mold. Name the route you have in mind and the quantity.
What should the drawing say?
The compound or an allowed resin list, the dimensions, the surface that matters and any medical or thermal duty that restricts substitutes. Attach the datasheet if a property is mandatory.
Does a PEEK page mean a shop has the material?
No. It is a specification guide. The project is how you ask Metraxio to find or qualify a manufacturer.
