Resin polyethylene (PE) polymers ne masu thermoplastic wanda ke nufin cewa ana iya samar da su da zafi kuma a sake narkewa ba tare da rasa halayensu na asali ba. Thermoplastics sun bambanta ta wannan hanyar da thermosets, waɗanda ke samun canji na dindindin bayan taurare.
An rarraba resin polyethylene zuwa manyan rukuni uku: ƙarancin yawa (LDPE), babban yawa (HDPE), da kuma babban nauyin kwayoyin halitta (UHMW-PE). Ana amfani da LDPE don yin jakunkunan siyayya na filastik, misali; HDPE, don bututun magudanar ruwa; da kuma, UHMW-PE don na'urorin likitanci. Gabaɗaya, girman yawan kayan, haka tsarinsa yake. Tsarin kristal mai girma yana da yanayin zafi mafi girma.
Ana iya kwatanta LDPE da ƙarancin ƙarfi amma yana da ƙarfi sosai, don haka yana ba shi damar miƙewa ba tare da ya karye ba. Yana da shahara a aikace-aikacen marufi iri-iri, tun daga kwalaben matsewa zuwa fim ɗin rufewa. HDPE yana da ƙarfi mafi girma amma yana da ƙarancin juriya, wanda hakan ke sa ya zama da amfani ga samfuran da dole ne su riƙe siffarsu kamar gwangwanin shara. HDPE yana ci gaba da aiki a -60°C. UHMW-PE yana da ƙarfi sosai, tare da rabon ƙarfi-da-nauyi kusa da na wasu ƙarfe. Yana da juriya mai yawa ga gogewa, ya dace da aikace-aikace na musamman kamar sukurori na lokaci da ƙafafun tauraro na injunan kwalba, kushin lalacewa na gidajen haɗin wucin gadi, da sauransu.
Kamar sauran na'urorin thermoplastics, resin polyethylene yana shan danshi cikin sauƙi. Ba sa buƙatar tsarin bushewa na musamman kafin a yi musu allura ko a yi musu wasu gyare-gyare.
Kayan da ke cikin siffarsa ta halitta yawanci fari ne ko baƙi kuma yana bayyana sosai idan aka rage girman kwalaben madara da makamantansu. Masu samar da kayayyaki za su iya daidaita tsarin don ƙara ƙarfin tsagewa, bayyananne, tsari, iya bugawa, da sauransu, kamar yadda ake buƙata don dacewa da aikace-aikacen da ake yi a hannu.

Ana iya sarrafa polyethylene ta hanyar busawa, fitar da shi, yin allurar ƙera da sauran hanyoyi, waɗanda ake amfani da su sosai wajen ƙera siririn fim, kayayyakin da ba su da ramuka, zare da abubuwan da ake buƙata na yau da kullun. Da sauransu.
(1) Ana amfani da fim ɗin polyethylene (PE) sosai a matsayin kayan marufi don abinci, magani, takin sinadarai, kayayyakin masana'antu da fim ɗin noma. Haka kuma ana iya fitar da shi zuwa fim ɗin haɗaka don tattara abubuwa masu nauyi.
(2) kayayyakin polyethylene hollow: ƙarfin polyethylene mai yawa ya fi girma, ya dace da kayayyakin hollow. Ana iya busa su cikin kwalabe, ganga, gwangwani, tankuna da sauran kwantena. Ko kuma ta hanyar jefa su cikin tankin tanki da tankin ajiya da sauran manyan kwantena.
(3) Bututun polyethylene da farantin sun dace da shimfidawa a ƙarƙashin ƙasa, tebur da kayan gini
(4) zare na polyethylene: ana iya amfani da shi azaman riguna masu hana harsashi. Kayan haɗin gwiwa don ayyukan mota da na ruwa.
(5) zare mai polyethylene don yin siliki mai laushi, siliki mai laushi ko zare mai fim, wanda ake amfani da shi wajen yin igiya, zane mai tacewa, zane mai marufi da sauransu.
(6) Miscellany na Polyethylene: Miscellany da ake samarwa ta hanyar allurar ƙera sun haɗa da nau'ikan furanni na yau da kullun, furanni na wucin gadi, akwatunan juyawa, ƙananan kwantena, sassan kekuna da tarakta, waɗanda ake amfani da su wajen ƙera sassan gini.
An tattara kayan a cikin buhunan filastik kilogiram 25, waɗanda za a iya jigilar su ta hanyar jirgin ƙasa ko ta ruwa kuma a adana su a cikin busasshen sito.
