Tsopano epoxypepalapamsika ungagawidwe m'magulu awiri: opanda halogen ndi opanda halogen. Halogen epoxypepalaimawonjezeredwa ndi fluorine, chlorine, bromine, ayodini, astatine ndi zinthu zina za halogen kuti zigwire ntchito poletsa moto. Ngakhale kuti halogen ndi yoletsa moto, ngati itapsa, imatulutsa mpweya wambiri woopsa, monga dioxins, benzofurans, ndi zina zotero, yokhala ndi kukoma kochuluka komanso utsi wambiri, n'zosavuta kuyambitsa khansa ikalowa m'thupi la munthu ndipo imawopseza kwambiri moyo ndi thanzi.

Epoxy yopanda Halogenpepala, kuti akwaniritse zotsatira za choletsa moto, chinthu chachikulu chomwe chimawonjezeredwa ndi phosphorous element nitrogen element. Pamene utomoni wa phosphorous watenthedwa, umatenthedwa ndikuwola kuti upange polyphosphoric acid. Polyphosphoric acid imatha kupanga filimu yoteteza pamwamba pa mbale ya epoxy, ndikuletsa kukhudzana mwachindunji ndi mpweya, mpweya wochepa, moto umazimitsidwa mwachilengedwe. Ndipo utomoni wokhala ndi phosphorous womwe uli mu kuyaka udzapanga mpweya wosayaka, ndikupangitsa kuti mphamvu ya choletsa moto ipitirire.

Kuwonjezera pa kukhala wosamala zachilengedwe komanso woletsa moto,epoxy yopanda halogenpepalaali ndi ubwino wina wambiri. Nthawi zambiri amagwiritsidwa ntchito ngatizinthu zotetezera kutentha, kotero magwiridwe antchito a kutchinjiriza ndi abwino kwambiri. Imatha kukhala gawo lothandizira komanso loteteza zinthu zosiyanasiyana zamagetsi, m'malo ovuta, monga chinyezi, kutentha kwambiri, komanso imatha kugwira ntchito bwino. Mapepala a epoxy opanda halogen alinso ndi kukhazikika kwabwino kwa kutentha, chifukwa cha zinthu za nayitrogeni ndi phosphorous, kuthekera kwa mamolekyu a nayitrogeni ndi phosphorous kuyenda akatenthedwa. Kuphatikiza apo, simatenga madzi, kusinthasintha kwamphamvu ndi zabwino zina.

Zaka zingapo zapitazo, European Union yaletsa kugwiritsa ntchito mapepala a epoxy opanda halogen, koma chifukwa cha mtengo wokwera wa epoxy yopanda halogen.mapepala, sichinagwiritsidwe ntchito kwambiri ku China, ndipo opanga ambiri akugwiritsabe ntchito halogen epoxypepalas. Chifukwa cha chitukuko cha chuma cha China komanso kukulitsa chidziwitso cha anthu pankhani yoteteza chilengedwe, anthu alandila bwino kwambiri ntchito yabwino ya bolodi la epoxy lopanda halogen. Ndikukhulupirira kuti posachedwa, lidzakhala lotchuka kwambiri.
