Protective ultra high-temperature jacket for polyimide (PI) coated fibers with applications in the extended temperature range of −100 °C to +260 °C

Compared with fibers only coated with polyimide and without a protective jacket, our ultra high-temperature jacket (UHTJ) offers much-improved abrasion resistance plus excellent mechanical properties for laying, and is very easy to strip during assembly. UHTJ covers a much larger temperature range than fibers with conventional ETFE or PFA jacket coatings, while also offering outstanding resistance to chemical degradation. Depending on the fiber dimension, the UHTJ is available in lengths of up to several kilometers.

The ultra high-temperature jacket can be combined with a wide range of existing fiber designs. Itsadvantages are best exploited in combination with polyimide-coated fibers – including fiber bundles. In addition, UHTJ also offers a non-conductive surface that is well-suited to use in EMC applications. Since the material does not outgas, it is also suitable for applications in a vacuum.  The ultra high-temperature jacket is easily strippable with a modest amount of force and has flawless edges. This makes fibers very easy to process. Within the specified temperature range, UHTJ is a low-cost alternative to metal coatings and can replace existing fibers.
