Umuforomo w'Impu Ebyiri Umuforomo wa Membrane ya ETFE ni umuforomo w'impu ebyiri wateguriwe inyubako y'ubushakashatsi n'iyigisha. Impu yo hanze igizwe n'amasitofu meza y'ethylene tetrafluoroethylene yashizweho ubushyuhe kugira ngo ahuze, afite ubugari bwa metero eshatu kandi agera ku burebure bwa metero mirongo itandatu na kabiri, agumizwa mu mikoro y'umwuka ihoraho kandi ashyirwa mu buryo bw'agambanyi ku nyubako y'icyuma y'inyongera hifashishijwe ibikoresho by'aluminium biboha. Umwanya uri hagati y'izo mpu ukora nk'ikusanyirizo ry'izuba, kandi umwuka ushyushye ujyanwa mu bikoresho by'ivunika ry'umwuka, bigatuma ingufu zikoreshwa zigabanuka kugera kuri 30 ku ijana. Iyo membrane isukurwa n'amazi y'imvura kandi ikongerera kandi umutekano w'amajwi uturuka ku muvuduko w'ibinyabiziga mu muhanda.
