PEEK Medical Tubing
Polyether Ether-Ketone (PEEK) is an engineering grade thermoplastic polymer with characteristics that are uniquely suited to many medical tubing applications. PEEK is a high purity, semi-crystalline, organic polymer with excellent resistance to thermal degradation at high temperatures. PEEK tubing exhibits high column strength, as well as high tensile strength and high flexural modulus, making it perfect for catheters and other tubing applications requiring good torque response and pushability.
Extruded PEEK tubing is used in medical applications where exceptionally high rigidity is needed. Due to PEEK’s excellent biocompatibility, it is a suitable choice for long-term implants. With a modulus similar to bone, PEEK is commonly used in orthopedic implant applications. PEEK tubing can also be found in medical applications requiring high vacuum or pressure holding capability. The material can serve as an effective alternative to steel, aluminum, glass, and other polymers, including use as a composite structure in reinforced catheter shafts.
Its low moisture absorption, chemical inertness, high abrasion and chemical resistance, biocompatibility, torsional stability, and excellent stability at elevated temperatures make PEEK a suitable material for many medical devices, including implants.
PEEK medical tubing is USP Class VI compliant.
