Wannan shine mafi amfani da BPADA na yau da kullun kuma mafi mahimmanci. BPADA an haɗa shi da monomers na diamine na yau da kullun kamar 4,4' -diaminodiphenyl ether (ODA) don samar da polyimide wanda ya haɗu da "juriyar zafi da sauƙin sarrafawa". Wannan nau'in kayan PI, saboda kasancewar haɗin ether da ƙungiyoyin isopropyl a cikin tsarin kwayoyin halittarsa, yana riƙe da juriyar PI mai zafi (zafin aiki na dogon lokaci 180-220℃). BPADA kuma ya fi sauƙin yin shi a cikin fina-finai, faranti, da sauransu fiye da PI na yau da kullun, kuma ana amfani da shi akai-akai a cikin:
