PEEK (Polyether Ether Ketone) Rods

PEEK (Polyether Ether Ketone) Rods are high-performance engineering thermoplastics known for their outstanding mechanical strength, thermal stability, and chemical resistance. PEEK rods are designed for extreme environments, capable of withstanding high temperatures up to 250°C (482°F), aggressive chemicals, and intense mechanical stress without compromising performance. They also offer excellent wear resistance, low friction, and superior dimensional stability, making them ideal for precision-engineered components.

Key Features:

High Temperature Resistance: Continuous use up to 250°C (482°F) with short-term peaks up to 300°C (572°F).
Exceptional Mechanical Strength: Maintains rigidity and durability under extreme conditions.
Chemical Resistance: Withstands harsh chemicals, acids, solvents, and hydrolysis.
Excellent Wear & Abrasion Resistance: Ideal for applications with high friction and heavy loads.
Low Friction & Self-Lubricating: Reduces wear in moving parts without external lubrication.
Flame Retardant: Naturally resistant to flames with low smoke and toxic gas emissions.
Dimensional Stability: Maintains shape and precision under thermal and mechanical stress.

Common Applications:

Aerospace & Defense: Structural components, insulation parts, seals, and bushings for high-stress environments.
Automotive Industry: Engine components, transmission parts, thrust washers, and high-performance bearings.
Medical Devices: Sterilizable surgical instruments, dental tools, and implantable devices (medical-grade PEEK).
Oil & Gas Industry: Valve seats, pump components, seals, and electrical connectors for high-pressure conditions.
Semiconductor & Electronics: Precision parts requiring high purity, chemical resistance, and electrical insulation.
Industrial Equipment: Gears, rollers, bushings, and custom-machined components for heavy-duty machinery.

FAQs – PEEK Rods

1. What is PEEK rod used for?

PEEK rods are used in aerospace, automotive, medical, oil & gas, and semiconductor industries for components like bushings, seals, bearings, gears, and precision parts due to their high strength and heat resistance.

2. How does PEEK handle high temperatures?

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

3. Is PEEK food-safe?

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

4. Can PEEK rods be machined?

Yes, PEEK rods can be easily CNC-machined, milled, turned, and drilled with precision, maintaining excellent dimensional stability.

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

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

6. Is PEEK chemically resistant?

Yes, PEEK is resistant to a wide range of chemicals, including acids, bases, solvents, and hydrocarbons, making it ideal for harsh industrial environments.

7. Is PEEK UV-resistant?

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