Fiber Optics I www.leoni-fiber-optics.com Ultra high-temperature jacket (UHTJ) for polyimide (PI) coated fibers Your advantages at a glance ■ Protective jacket for applications in the extended temperature range of –100 °C to +260 °C Extended temperature range from –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 Excellent mechanical properties Very low coefficient of friction laying, and is very easy to strip during assembly. UHTJ covers Excellent strippability a much larger temperature range than fibers with conventional ETFE Outstanding resistance to chemical degradation Self-extinguishing, flame retardant Low-cost alternative to metal coatings (UHTJ) offers a much broader temperature range of −100 °C to +260 °C. (aluminum, gold) While commercially available PFA jackets based on elastic polymers are improved abrasion resistance plus excellent mechanical properties for 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. Compared with alternative materials, an ultra high-temperature jacket usable across a similar temperature range, they are unable to meet key contemporary user requirements such as cost-effective cable stripping. Wider temperature ranges than the range offered by PI-coated fibers are possible only by using expensive metal coatings. Please talk to us about options for customized cables combined with the new ultra high-temperature jacket – we will be happy to work with you on a solution tailored to your application needs.
