Ishubhu encibilikayo enamathela odongeni enamathelayo futhi esindayo yenziwe nge-polyolefin ebuyisela amalangabi ekhishwe ngongqimba lwe-adhesive encibilikayo eshisayo ngaphakathi. Isetshenziswa kabanzi ekuvikelweni kwe-cable splice kanye nokuvikela ukugqwala kwamapayipi ensimbi. I-polyolefin yangaphandle kanye nongqimba oluqinile lwangaphakathi lwe-adhesive encibilikayo eshisayo inganikeza isivikelo sesikhathi eside nesithembekile sezinto ezisendaweni yangaphandle.Izinga lokushisa eliqhubekayo lokusebenza lifanele Minus 55°C kuya ku-125°C.Isilinganiso sokuncipha singafinyelela ku-3.5:1.
