Machubu apakati komanso olemetsa okhala ndi zomatira zomata kutentha amapangidwa ndi polyolefin yotchinga moto yotuluka ndi wosanjikiza wa zomatira zotentha zosungunuka mkati. Amagwiritsidwa ntchito kwambiri poteteza chingwe cha splice ndi chitetezo cha chitoliro chachitsulo. Polyolefin akunja ndi wosanjikiza wamkati wandiweyani wa zomatira zotentha zosungunuka zimatha kupereka chitetezo chanthawi yayitali komanso chodalirika pazinthu zakunja.Kutentha kosalekeza kogwira ntchito ndikoyenera Minus 55°C kufika pa 125°C.
