Leliqiniso lezibuko zokulayisha kubonakala kakhulu emehlweni yemfundo kodwa zinezimiso ephathelene ngokwehlukile. Isibuko sokulayisha sikhulu sikhiwe ukuthola ukunqamuka okudala kumalini amakhaza (isb. isore esikhweshisiwe, ikhlinika elikhazimula ekwaleni kwi-180°C-250°C). Amaphambili awo anjengama-compound akhethekile njenge-EPDM (Ethylene Propylene Diene Monomer), angavuthi ukugcina, ukuphunga nokushisa. Isibuko sokulayisha senzulu, ngakho-ke, siseduze kokugcina ubunzima bokusebenza phantsi kwezizinda ezihlanzekileyo (ngokuvamile ku-120°C), ukuvikela amaphambi ukungabi nomdla wokudala ngenkathi iphinde iphule izizinda. Zombili zibalulekile emisebenzini njengekulayisha umlilo wezimali zomthwalo noma izinto emsakathini wokuhlanganisa.
