PEEK Tubing High-Performance Engineering Plastic Tubing
High-Temperature Resistance
PEEK tubing is a high-performance engineering plastic tubing
made from resin through precision extrusion or injection molding. It features high-temperature resistance (long-term use at 260°C),
chemical inertness, high strength, low friction coefficient. Its core value lies in replacing metals and traditional plastics in
extreme environments, widely applied in semiconductors, medical,
energy, and aerospace sectors.

Product features of PEEK tubing
1. Extreme Temperature Resistance:
- Long-term stability up to 260°C, short-term resistance up to 300°C.
- No brittleness at -196°C, suitable for cryogenic applications.
2. Chemical Stability:
- Resists strong acids (e.g., concentrated sulfuric acid), alkalis,
and organic solvents (except limited exceptions).
- Hydrolysis resistance ensures performance in high-temperature,
high-pressure steam.
3. Mechanical Superiority:
- Tensile strength ≥150 MPa, fatigue resistance surpassing metals and
general plastics.
- Low friction coefficient (self-lubricating) reduces energy loss and
wear.
4. Biocompatibility & Safety:
- Non-toxic, non-allergenic, and compatible with autoclaving, gamma
irradiation, and ethylene oxide sterilization.
- FDA food-grade certification for food processing equipment.
5. Dimensional Stability:
- Low thermal expansion coefficient (close to aluminum), ensuring
precision in high-temperature applications.
6. Environmental Safety:
- Low smoke and toxic gas emissions during combustion.
Key applications of PEEK tubing
1. Semiconductors & Electronics:
- Wafer Transport Pipelines: Deliver ultra-pure water/chemicals
without metal ion contamination.
- Insulation Components: Maintain electrical insulation in
high-frequency, high-voltage environments (e.g., connectors,
electronic packaging).
2. Medical & Biotechnology:
- Surgical Instruments: Autoclavable catheters and endoscopic
components.
- Implants: Artificial bones, dental instruments (alternative to
titanium alloys).
3. Energy & Chemicals:
- Oil & Gas Piping: Corrosion-resistant seals and wear-resistant
bushings (metal replacement).
- Fuel Cells: High-temperature proton exchange membrane supports.
4. Automotive:
- Engine Components: Heat-resistant seals, bearings (reduces
friction and energy consumption).
- EV Batteries: Cooling system tubing (electrolyte corrosion
resistance).
5. Aerospace:
- Engine Parts: Lightweight, high-temperature-resistant
components (titanium/aluminum alternatives).
- Satellite Components: Radiation-resistant insulation materials.
FAQ of medical PEEK tubing
1. Q: What is the maximum continuous operating temperature of
PEEK tubing?
