What is PEEK Tubing?

PEEK tubing (polyetheretherketone) is a tubing made from the high-performance thermoplastic polymer PEEK. Its exceptional performance excels in numerous demanding applications. It's more than just tubing; it's a key component in solving complex engineering challenges. The unique properties of PEEK give tubing unparalleled advantages, enabling it to remain stable in high-temperature, high-pressure, and high-strength environments.

Exceptional Properties of PEEK Tubing

The most notable feature of PEEK tubing is its exceptional high-temperature resistance. It can operate reliably in environments up to 250°C while maintaining excellent mechanical properties, including high strength, high fracture toughness, and stable dimensional stability. Even under extreme thermal conditions, PEEK tubing performs reliably without deformation or performance degradation.

In addition to high-temperature resistance, PEEK tubing exhibits exceptional chemical stability, abrasion resistance, and flame retardancy. Its excellent biocompatibility makes it a leading choice in medical devices, enabling them to be safely implanted in the human body or used in contact with living organisms.

Wide Applications of PEEK Tubing

Due to its exceptional properties, PEEK tubing has a wide range of applications. In the medical field, it is a core component in high-precision medical devices, such as:

• Cardiovascular interventional catheters: Due to high strength and biocompatibility.
• Endoscopes and urological catheters: Flexibility and durability ensure smooth procedures.
• Electrosurgical forceps: Excellent insulating properties ensure safety.
  
  

PEEK tubing is also used in other demanding industries. In the e-cigarette industry, it serves as thermal insulation tubing. In military and aerospace applications, its lightweight, high strength, and resistance to extreme environments make it essential for critical systems in aircraft and spacecraft.

Dimensional Tolerances of PEEK Tubing

PEEK tubing is typically produced using high-precision extrusion technology, allowing very tight dimensional tolerances. Experienced manufacturers ensure that outer diameter, inner diameter, and wall thickness remain within strict limits. This precision is crucial for medical catheters and aerospace components, requiring precise fit and consistent performance.

Advantages Over Other High-Performance Tubing Materials

Compared to common materials like PTFE (polytetrafluoroethylene) and PVDF (polyvinylidene fluoride), PEEK tubing offers significant advantages in mechanical strength, rigidity, and high-temperature resistance. In applications requiring high load-bearing capacity and dimensional stability, especially under extreme conditions, PEEK tubing provides more reliable and long-lasting performance.
