ETFE vs PTFE

Ethylene tetrafluoroethylene (ETFE) bụ plastik nke dabeere na fluorine.Emebere ya ka ọ nwee nnukwu nguzogide corrosion na ike karịa oke okpomọkụ.ETFE bụ polymer na aha ya dabeere na ya bụ poly (ethene-co-tetrafluoroethene).ETFE nwere okpomọkụ na-agbaze dị elu, kemịkalụ mara mma, ọkụ eletrik na ihe ndị na-eguzogide ike radieshon.Mgbe ọkụ, ETFE na-ahapụ hydrofluoric acid.
