PEEK rods are-section profiles made from polyetheretherketone (P resin through extrusion molding. As rod-shaped profiles, they are primarily used for manufacturing small-batch or geometrically complex PEEK components that are difficult to produce via injection molding, through precision machining.
**Core Properties of PEEK Rod
- High-Temperature Resistance: Can operate long-term at 260°C short-term tolerance up to 310°C. melting point reaches 334°C, and glass is 143°
- High Strength & Hardness: Maintains considerable strength at elevated temperatures, with a flexural strength of around 24MPa at°C.
Wear Resistance & Self-Lubrication**: Exhibits outstanding tribological properties—low friction and high wear resistance—making it ideal for dynamic applications like bearings and seals. - Chemical Resistance: Nearly impervious to all chemicals sulfuric acid, with corrosion resistance comparable to nickel steel.
- Dimensional Stability: Extremely low water absorption and thermal expansion coefficient close to aluminum, ensuring excellent dimensional stability.
- Flame Retardancy & Low Smoke: Achieves UL-0 rating without additives, with minimal smoke and toxic gas emission.
Primary Applications
PEEK rods are widely used in industries demanding performance:
- A: Structural and connecting components in aircraft and satellites.
- Medical Devices: Surgical instruments, implants (e.g., spinal fusion cages), sterilization trays, favored for biocompatibility and X-ray translucency.
- Sem & Electronics: Wafer handling trays, test sockets, insulating parts.
- & Gas**: High-temperature/pressure/corrosion-resistant seals, valve seats, pump wear rings.
-cision Machinery & Automotive**: High-performance bearings, gears, gaskets, compressor valve plates.
