PEEK Capillary Tubes

Biocompatible PEEK Capillary Tubes

Medical PEEK capillary tubing is a type of small, thin tube made of polyether ether ketone (PEEK) material that is specifically designed for use in biomedical applications. It is biocompatible, meaning it does not cause any adverse reactions when implanted in the body, and is commonly used in medical devices such as catheters and implants. PEEK capillary tubing is known for its high strength, durability, and resistance to chemicals and heat, making it an ideal choice for biomedical applications where reliability and performance are critical. With its excellent mechanical properties and biocompatibility, medical PEEK capillary tubing is the perfect solution for a wide range of medical applications.
