Umbhobho we-HDPE luhlobo lombhobho weplastiki oguquguqukayo osetyenziselwa ukuhambisa ulwelo kunye nerhasi kwaye uhlala usetyenziselwa ukufaka endaweni yekhonkrithi endala okanye imibhobho engundoqo yentsimbi. Yenziwe kwi-HDPE ye-thermoplastic (i-polyethylene ephezulu yoxinaniso), inqanaba layo eliphezulu lokunganyanzeki kunye ne-molecular bond elomeleleyo lenza ukuba ilungele imibhobho yoxinzelelo oluphezulu. Umbhobho we-HDPE usetyenziswa kwihlabathi jikelele xa kusenziwa izicelo ezifana neentsinjana zamanzi, oovimba begesi, oomatshini bogutyulo, iintambo zokuhambisa uludaka, unkcenkceshelo lwasemaphandleni, iintambo zobonelelo lwenkqubo yomlilo, umjelo wombane kunye nonxibelelwano, kunye nemibhobho yamanzi esiphango nemibhobho yokuhambisa amanzi.
