PEEK Plastic

---

Known under the chemical name polyetheretherketone, PEEK is a quality, high-performing engineering plastic suitable for a broad range of engineering applications.

PEEK finds use in mechanical engineering, automotive and general machinery construction. Examples include plain bearings, coil bodies, guide & clutch parts, gears, cams, rollers, slide bearings, seal rings and guide rails, pulleys & conveyors.

Benefits:

Typical commercial applications include:

• Optimised for application suitability
• Superior all-round product for various applications
• Ability to operate in the most demanding applications and performance conditions
• Perfect for components requiring tight manufacturing tolerances

Machinability

The machinability of un-modified PEEK is excellent. The glass or carbon fibre reinforced grades will require tipped tooling. As with all plastic materials, experience has shown that extra care must be taken with larger diameters, especially in the colder months when plastic materials lose some of their toughness, and so have less resistance to machining stresses. We supply full machining instructions on request.

Chemical Resistance

PEEK has good resistance to water and water vapour (un-filled material has excellent hydrolysis resistance), alcohols, esters, alkaline solutions, oils, fats and fuels. It is not resistant to sulphuric acid, nitric acid, halogens, or MEK at raised temperatures.

Availability

We stock PEEK plastic in extruded round bars, extruded sheets/plates and tubular bars.
