Makampani opanga mapulasitiki ali ndi zaka zoposa 100, koma polyethylene sinapangidwe mpaka zaka za m'ma 1930. Chiyambireni discovenin 1933, Polyethylene (PE) yakula kukhala imodzi mwazinthu zogwiritsidwa ntchito kwambiri komanso zodziwika bwino za thermoplasticmaterials. Masiku ano utomoni wamakono wa PE umapangidwa mwaluso kwambiri kuti ugwiritse ntchito movutikira kwambiri monga gasi woponderezedwa ndi mapaipi amadzi, zotayirapo, matanki amafuta agalimoto ndi zinthu zina zofunika kwambiri. Polyethylene (PE) ndi ya gulu ili. ndi semicrystaline thermoplastic. Poiyethyiene ndiye polima wodziwika bwino kwambiri. Mankhwalawa ndi awa: (CH2-CHz)nNdi mankhwala a hydrocarbon ogwirizana ndi chilengedwe.
CHANGRONGndi kampani yophatikizira yogawana ndi malonda, yomwe idakhazikitsidwa mu 2005 yomwe imayang'ana kwambiri kupanga mapaipi a HDPE, Fittings & Valves, PPR Pipes, Fittings & Valves, PP compression fittings & Valves, ndi malonda a Pulasitiki Pipe Welding makina, Zida za Chitoliro, Pipe Repair Clamp ndi zina zotero.
