PE polyethylene yas, lub hauv paus yas, hnab yas thiab lwm cov yas yas yog PE.
HDPE high-density polyethylene yas, lus Askiv "High Density Polyethylene", hu ua "HDPE.HDPE" yog ib hom qaum crystallinity, tsis muaj tho polar thermoplastic. Tus thawj lub xeev ntawm HDPE kua dawb tsos, hauv seem me me nyob rau hauv ib cov degree ntawm translucent.PE muaj kev ywj siab zoo rau feem ntau ntawm lub neej thiab kev lag luam tshuaj lom neeg. Qee hom tshuaj yuav tsim cov tshuaj lom neeg muaj corrosion, xws li oxidant oxidant (nitric acid), hydrocarbons (xylene) thiab hydrogen carbon (halogenated hydrocarbons) (carbon tetrachloride). Lub polymer tsis hygroscopic thiab muaj zoo waterproof chav, yuav siv tau nyob rau hauv daim ntawv thov ntim.HDPE muaj hluav taws xob zoo, tshwj xeeb tshaj yog dielectric hluav taws xob siv siab, yog li nws yog haum rau xaim thiab cable. Nruab nrab mus rau siab qib high school molecular qib tau zoo heev tej zaum kuj, txawm nyob rau hauv chav tsev kub hauv-40F tsawg kub li.
HDPE yeeb nkab yog ib qho thermoplastic polyolefin uas tau los ntawm ethylene copolymer. Txawm hais tias HDPE twb tau pib rau xyoo 1956 lawm, txoj yas no tseem tsis tau txog nws qhov kev paub tab. Cov khoom siv no tseem tab tom tsim nws cov kev siv tshiab thiab kev lag luam
