PEEK medical catheter is different from traditional medical catheters. In addition to good toughness, there is a certain rigidity.

PI Capillary – Good biocompatibility; – Long-term temperature resistance of 300°C; – Dielectric constant 3.0, surface resistivity 6.9*1014Ω.m; – The breakdown voltage for a thickness of -1mm is 18KV. – It has good guiding properties and an elastic modulus ranging from 3 to 4.5GPa。 Extruded PI catheter(TPI) It is rather complex. PI is sensitive to temperature and the environment. The suitable thickness of the pipe material is above 0.05mm. The wall thickness can be made thicker and continuous. It can be made into coiled tubing, with no solvent residue and no release agent residue. It also has better toughness (linear structure).   Dip-coated PI tubing It is relatively simple and widely used in industry. The enameled wire process is suitable...
