Mapulasitiki ambiri ali ndi mphamvu yolimbana ndi dzimbiri ku asidi, alkali, mchere, ndi zina zotero kuposa zitsulo ndi zinthu zina zopanda chilengedwe, ndipo ndi oyenera kwambiri zitseko ndi mawindo, pansi, makoma, ndi zina zotero m'mafakitale a mankhwala; mapulasitiki a thermoplastic amatha kusungunuka ndi zinthu zina zachilengedwe, pomwe mapulasitiki otenthetsera kutentha sasungunuka, koma kutupa pang'ono kungachitike. Mapulasitiki alinso ndi mphamvu yolimbana ndi dzimbiri ku madzi ozungulira, salowa madzi ambiri, ndipo angagwiritsidwe ntchito kwambiri m'mapulojekiti osalowa madzi komanso osanyowa.
Chitoliro cha PE(HDPE payipi) imapangidwa ndi polyethylene ngati chinthu chachikulu chopangira zinthu zopangira, kuwonjezera ma antioxidants, carbon black ndi zinthu zopaka utoto. Imadziwika ndi kukhuthala kochepa, mphamvu yayikulu, kukana kutentha kochepa komanso kulimba, ndipo kutentha kwa embrittlement kumatha kufika -80 °C.
Pulasitiki ya PEZingathe kukonzedwa ndikupangidwa pogwiritsa ntchito njira zosiyanasiyana zopangira zinthu zosiyanasiyana monga mafilimu, mapepala, mapaipi, ma profiles, ndi zina zotero; ndipo ndizosavuta kudula, kumangirira ndi kukonza "zowotcherera". Pulasitiki ndi yosavuta kuipaka utoto ndipo imatha kupangidwa kukhala mitundu yowala; ingathenso kukonzedwa posindikiza, kuyika ma electroplating, kusindikiza ndi kuyika ma embossing, zomwe zimapangitsa kuti mapulasitiki akhale ndi zokongoletsa zambiri.
Kukana kutentha kwaMapulasitiki a mapaipi a PENthawi zambiri sizikhala zokwera kwambiri. Zikayikidwa pamoto wotentha kwambiri, zimafewa ndi kusokonekera, kapena kuwola ndi kuwonongeka. Kutentha kwa kutentha kwa ma thermoplastics wamba ndi 60-120 °C, ndipo mitundu yochepa yokha ndi yomwe ingagwiritsidwe ntchito kwa nthawi yayitali pafupifupi 200 °C. Mapulasitiki ena ndi osavuta kugwira moto kapena kuyaka pang'onopang'ono, ndipo utsi wambiri wa poizoni umapangidwa ukayaka, zomwe zimapangitsa kuti nyumba ziwonongeke pamene moto ukuyaka. Coefficient of linear expansion ya pulasitiki ndi yayikulu, yomwe ndi yayikulu nthawi 3-10 kuposa ya chitsulo. Chifukwa chake, kutentha kumachepa kwambiri, ndipo zinthuzo zimawonongeka mosavuta chifukwa cha kuchuluka kwa kutentha.
Chifukwa cha kutentha kwake kochepa komanso kulimba kwake, imatha kupirira kuwonongeka kwa kugwedezeka kwa magalimoto ndi makina, kuzizira ndi kusungunuka komanso kusintha kwadzidzidzi kwa kuthamanga kwa ntchito. Chifukwa chake, mapaipi ozungulira angagwiritsidwe ntchito pomanga kapena kupumira, zomwe ndizosavuta kumanga komanso mtengo wotsika waukadaulo; Khoma la mapaipi ndi losalala, kukana kwapakati ndi kochepa, kugwiritsa ntchito mphamvu kwa chonyamulira ndi kochepa, ndipo sichimawonongeka ndi mankhwala amadzimadzi a hydrocarbon omwe ali mu chonyamulira. Kuchuluka kwapakati komanso kwakukuluMapaipi a PEndi oyenera mapaipi a gasi ndi gasi wachilengedwe mumzinda. Mapaipi a PE otsika kwambiri ndi oyenera mapaipi amadzi akumwa, machubu a chingwe, mapaipi opopera a zaulimi, mapaipi opopera madzi, ndi zina zotero. Mapaipi a PE angagwiritsidwenso ntchito popereka madzi, madzi otayira madzi ndi njira zotulutsira mpweya m'migodi.
CHANGRONGndi kampani yogwirizana ndi makampani ogulitsa magawo ndi malonda, yomwe idakhazikitsidwa mu 2005 yomwe imayang'ana kwambiri pakupanga Mapaipi a HDPE, Zolumikizira ndi Ma Vavu, Mapaipi a PPR, Zolumikizira ndi Ma Vavu, Zolumikizira ndi Ma Vavu a PP, komanso kugulitsa makina olumikizira mapaipi apulasitiki, Zida za mapaipi, Cholumikizira Chokonza Mapaipi ndi zina zotero.
