Frequently Asked Questions

What are PEEK sheets and what are they used for?

PEEK sheets are high-performance engineering plastics used in extreme mechanical, chemical, and thermal environments. Typical applications include aerospace components, semiconductor equipment, oil and gas parts, medical devices, electrical insulation panels, wear plates, and precision-machined industrial components.

What applications are PEEK sheets best suited for?

PEEK sheets are used for high-temperature structural parts, chemical processing equipment, bearing and wear components, valve seats, compressor parts, medical trays, and electrical insulation where strength, cleanliness, and long-term stability are required.

What are the key properties of PEEK sheet?

PEEK sheet offers very high mechanical strength, excellent chemical resistance, low moisture absorption, outstanding dimensional stability, and continuous operating temperatures up to around 250°C. It also performs well under load and has good wear and fatigue resistance.

Can PEEK sheets be machined or fabricated?

Yes. PEEK sheets can be CNC machined, drilled, milled, and turned into precision components. Due to material cost and hardness, sharp tooling and controlled machining parameters are essential to achieve accurate parts and minimise waste.

How does PEEK sheet compare to other engineering plastics?

PEEK outperforms plastics such as nylon, acetal, PETP, and PTFE in high-temperature, high-load, and chemically aggressive environments. It maintains strength and tolerances where other plastics soften or creep. The main limitation is cost, which is significantly higher than standard engineering plastics.
