EPE (ExpandableClimatic Tests) polyethylene ce mai cirewa, kuma aka sani da ulun lu'u-lu'u.Rufaffen tantanin halitta ba tare da haɗin kai ba, babban samfuri ne mai kumfa polyethylene wanda aka samar ta hanyar extrusion na ƙananan yawa polyethylene (LDPE) azaman babban albarkatun ƙasa.
EPE yana da babban elasticity da farar bayyanar.Domin jikin kumfa ne mai cikakken zaman kanta, yana da haske kuma yana iya tanƙwara, don haka yana da tasirin tarwatsawa da buffering tasirin tasiri.Bugu da ƙari, EPE kuma yana da halaye na kiyaye zafi, daɗaɗɗen danshi, zafi mai zafi, sautin sauti, rashin ƙarfi, tsufa, juriya na lalata da sauransu.Wadannan abũbuwan amfãni sa EPE lu'u-lu'u auduga ne a hankali maye gurbin gargajiya marufi kayan, yadu amfani a kowane fanni na rayuwa a anti-fall, anti- karo, anti-tasiri marufi.
Tsarin samar da EPE da fasaha
Samar da EPE ya haɗa da sassa uku: ɓangaren auduga mai mirgina, ɓangaren sarrafa auduga mai zurfi da ɓangaren audugar lu'u-lu'u.Bi da bi, kowane bangare ya ƙunshi ƙananan sassa da yawa, kamar yadda aka nuna a ƙasa:
