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, LEONI‘s 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 new ultra-high-temperature jacket (UHTJ) offers additional protection for fibers coated with polyimide (PI), silicone and high-temperature acrylate. It provides advantages such as outstanding chemical stability,flame-retarding,excellent mechanical properties.With its ultra high-temperature jacket (UHTJ), LEONI has developed a mechanically rugged product that offers an industry-optimized solution for many applications, even though its −100 °C to +260 °C temperature range does not quite match that for polyimide.
