PEEK (Polyether Ether Ketone) Sheet

PEEK (Polyether Ether Ketone) Sheets are high-performance engineering thermoplastics known for their exceptional mechanical, thermal, and chemical resistance properties. PEEK sheets are ideal for demanding applications where strength, durability, and heat resistance are critical.

Key Features:

High Temperature Resistance: Can withstand continuous operating temperatures up to 250°C (482°F), with short-term exposure up to 300°C (572°F).
Exceptional Mechanical Strength: Maintains rigidity and strength even under extreme conditions.
Chemical & Hydrolysis Resistance: Resistant to aggressive chemicals, acids, and organic solvents, as well as steam and hot water.
Excellent Wear & Abrasion Resistance: Ideal for applications requiring long-term durability in harsh environments.
Low Friction & Self-Lubricating: Suitable for high-load, high-speed applications where reduced wear and friction are needed.
Flame Retardant: Naturally flame-resistant with low smoke and toxic gas emissions.

Common Applications:

Aerospace & Defense: Structural components, seals, and insulation parts exposed to extreme conditions.
Automotive Industry: High-performance engine components, transmission parts, and electrical connectors.
Medical Devices: Sterilizable surgical instruments and implantable devices (medical-grade PEEK).
Oil & Gas: Seals, bushings, valve components, and pump parts for high-pressure, high-temperature environments.
Semiconductor Industry: Precision parts that require high purity, chemical resistance, and dimensional stability.
Food Processing Equipment: FDA-compliant PEEK grades for food-safe machinery components.

FAQs – PEEK Sheets

1. What is PEEK used for?

PEEK is used in high-performance applications across industries like aerospace, automotive, medical, oil & gas, and electronics due to its thermal stability, chemical resistance, and mechanical strength.

2. Can PEEK withstand high temperatures?

Yes, PEEK can handle continuous temperatures up to 250°C (482°F) and short-term peaks up to 300°C (572°F) without losing its properties.

3. Is PEEK food-safe?

Yes, FDA-compliant grades of PEEK are available for food processing and medical applications.

4. How does PEEK compare to PTFE (Teflon)?

While PTFE offers better chemical resistance and lower friction, PEEK provides superior mechanical strength, wear resistance, and higher temperature tolerance.

5. Can PEEK be machined?

Yes, PEEK can be CNC-machined, milled, turned, and drilled with standard equipment. It maintains dimensional stability even after machining.

6. Is PEEK expensive?

PEEK is more expensive than standard plastics due to its high-performance properties, but it offers long-term cost savings in demanding applications where durability and reliability are critical.

7. Is PEEK UV resistant?

PEEK has moderate UV resistance. For prolonged outdoor exposure, UV-stabilized grades are recommended.
