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.
