Isihlukanisi sebhethri se-Fiberglass sihlukanisa umzimba webhethri kanye ne-electrolyte, edlala indima yokuhlukanisa, ukuqhuba kanye nokwandisa amandla ebhethri. Isihlukanisi sebhethri asikwazi nje ukuthuthukisa ukusebenza kwebhethri, kodwa futhi sithuthukise ukusebenza kokuphepha kwebhethri, ukuqinisekisa ukusebenza okuzinzile kwebhethri. Isihlukanisi impahla ngokuyinhloko fiberglass, ukujiya yayo ngokuvamile 0.18mm ukuze 0.25mm. Isihlukanisi sebhethri ye-Fiberglass njengengxenye ebalulekile yebhethri, idlala indima ebalulekile ebhethri. Izinhlobo ezahlukene zezihlukanisi zamabhethri zinezinzuzo zazo kanye nokubi futhi zifanele izimo ezihlukene zohlelo lokusebenza. Ukukhetha okufanelekile kwesihlukanisi sebhethri le-fiberglass akugcini nje ngokuthuthukisa ukusebenza kwebhethri, kodwa futhi kunciphisa amathuba okulimala kwebhethri, ngaleyo ndlela kukhulise impilo yesevisi nokuphepha kwebhethri.
