High-density polyethylene yog abbreviated li "HDPE". HDPE yog crystalline heev, uas tsis yog-polar thermoplastic cob. Cov tsos ntawm thawj HDPE yog milky dawb, thiab nws yog translucent mus rau ib tug tej yam nyob rau hauv lub nyias seem. PE muaj kev tiv thaiv zoo rau feem ntau ntawm cov tsev neeg thiab cov khoom siv tshuaj. Qee hom tshuaj muaj tshuaj lom neeg, xws li corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), thiab halogenated hydrocarbons (carbon tetrachloride). Cov polymer yog non-hygroscopic thiab muaj dej vapor tsis kam rau cov ntawv ntim khoom. HDPE muaj cov khoom siv hluav taws xob zoo, tshwj xeeb tshaj yog cov rwb thaiv tsev siab dielectric zog, ua rau nws zoo heev rau cov xov hlau thiab cables. Cov qib nruab nrab mus rau qib siab molecular hnyav muaj qhov cuam tshuam zoo heev ntawm qhov kub thiab txias thiab txawm tias qis li -40F.
