Thermoset Polyimide
Materials
The mechanical, thermal, chemical, radiation properties and tight tolerances of thermoset polyimide tubing are unmatched by any other material. PolyMedex polyimide tubing has been tested and certified to pass Class VI biocompatibility testing. Polyimide tubing is available in a variety of colors and can include PTFE additives for improved chemical resistance and lubricity.
Configurations
While pure polyimide tubing is available only in single lumen configurations, one or more polyimide tubes may be incorporated into a multi-lumen thermoplastic extrusion as lumen lining. Diameters range from 0.007” to 0.080” (0.152mm to 2.286mm) with wall thicknesses ranging from 0.0002” to 0.010” (0.005mm to 0.254mm). Profile shapes such as ellipses and rectangles with consistent wall thicknesses are also available.
Thermoset polyimide tubing can be reinforced with stainless steel wires in coil and/or braid configurations. Coil reinforcement provides resistance to collapse and buckling, while braid reinforcement improves burst strength and torque transmission.
