Application area

Chemistry: For corrosive and aggressive media, for laboratory probes, for micro analysers and titrators, for fluid and gas flow transport in chemical-analytical and biomedical systems.

Electronics and electrical engineering: Connection of microcables, insulation of microcables (coaxial cables), high-temperature insulation, micro coil forms, sheathing and plug-in channel for micro glass-fibre (laser) optics, micro sensors, precision micro slip rings.

Computer, nuclear engineering: For use in systems with maximum packing density, for reduction of weight and for applications where radiation of high energy density (nuclear radiation, X-ray radiation) occurs.

Precision mechanics: Micro bowden cable bushing, guide post for magnetic tape cassettes, heat protection, roller cover, micro pipes for fluids (e.g. ink).

Product specification

Polyimide micro tubing is absolutely seamless and non-porous. It has smallest inside diameters and wall thicknesses, in the range of 0.102 to 1.151 mm and 0.019 to 0.0508 mm respectively. Despite the extremely high wall stiffness the tubing can be bended springily to small radii.

PI micro tubing is chemically resistant and is usually used in applications where fluoroplastic tubing (e.g. PTFE tubing) is preferred.

Its chemical resistance combined with its mechanical, electrical, and thermal stability is outstanding.

Its manufacturing tolerances are extremely low leading to an excellent dimensional stability.

At overheating no toxic decomposition products are formed, as it is the case with fluoroplastics limiting there the number of applications. This problem does not occur with PI micro tubing.
