Small-Diameter Microtubes

Small-Diameter Microtubes

International Polymer Engineering is producing small-diameter microtubes and profiles made of KetaSpire polyetheretherketone (PEEK) resin from Solvay Advanced Polymers LLC for the medical industry. Microtubes made of KetaSpire PEEK offer greater strength and rigidity than PTFE microtubes and are easier to work with than those made of stainless steel. They are used in a range of medical applications including catheters, endoscopic working channels and laparoscopic instruments. IPE has produced microtubes made of unfilled KetaSpire KT-820 NT PEEK in sizes of 0.029 OD by 0.016 inch ID (0.74 OD by 0.41mm ID) and 0.077 OD by 0.057 inch ID (1.96 OD by 1.45 mm ID). The company can make PEEK tubes with up to a 0.25 inch (6.35 mm) diameter. IPE manufactures the microtubes on a 1 inch extruder specially designed for high-temperature materials like PEEK, which process at very high melt temperatures in the range of 370C (700F). IPE also has the capacity to manufacture PEEK profiles, both open and hollow, for a wide range of applications.

KetaSpire PEEK is a chemically resistant plastic and offers strength, fatigue resistance and a continuous-use temperature of 240C (464F). It can withstand more than 1,000 cycles of steam sterilization without any significant loss of properties and is also compatible with other sterilization methods, including ethylene oxide, vaporized hydrogen peroxide and gamma radiation. Based on biocompatibility testing as defined by ISO 10993-1, KetaSpire PEEK demonstrates no evidence of cytotoxicity, sensitization, intracutaneous reactivity or systemic toxicity.
