Kev lag luam yas muaj ntau tshaj 100 xyoo, tab sis polyethylene tsis tau tsim txog rau xyoo 1930. Txij li thaum nws tau tshawb pom xyoo 1933, Polyethylene (PE) tau loj hlob los ua ib qho ntawm cov khoom siv thermoplastic uas siv dav tshaj plaws thiab lees paub thoob ntiaj teb. Cov PE resins niaj hnub no tau tsim kho kom zoo rau cov ntawv thov uas nyuaj dua xws li cov kav dej thiab cov kav dej siab, cov ntawv pov tseg, cov roj tsheb thiab lwm yam ntawv thov uas xav tau. Cov polymers uas tsuas muaj carbon thiab hydrogen hu ua polyolefins. Polyethylene (PE) yog ib feem ntawm pawg no. nws yog semicrystaline thermoplastic. Poiyethyiene yog cov polymer txheem paub zoo tshaj plaws. Cov mis tshuaj yog: (CH2-CHz) nNws yog cov khoom hydrocarbon uas zoo rau ib puag ncig.
CHUANGRONGyog ib lub tuam txhab sib koom ua lag luam thiab kev lag luam, tsim muaj xyoo 2005 uas tsom mus rau kev tsim cov kav dej HDPE, Fittings & Valves, PPR Pipes, Fittings & Valves, PP compression fittings & Valves, thiab muag cov tshuab vuam yas, cov cuab yeej yeeb nkab, cov cuab yeej kho yeeb nkab thiab lwm yam.
